Two distinct pigments have been identified in the secretions, one red (hipposudoric acid) and one orange (norhipposudoric acid). Other threats are habitat loss due to the encroachment of human settlements and the diversion of river water for agriculture. Genetic evidence suggests that common hippos in Africa experienced a marked population expansion during or after the Pleistocene, attributed to an increase in water bodies at the end of the era. Of these, the Cyprus dwarf hippo survived until the end of the Pleistocene or early Holocene. [101] In 1987, the Toledo Zoo saw the first underwater birth by a captive hippo. More dangerous than a lion? While they have long been considered herbivores because they primarily feed on vegetation, they have no problem killing and eating other animals like impala, wildebeest and even other hippos. In fact, hippos are responsible for almost 3,000 human deaths a year. [108], Hippos have been the subjects of various African folktales. The hippo lost most of his hair and was too embarrassed to leave the water. Hippos spend most of their day in water close to shore lying on their bellies. [103], A red hippo represented the Ancient Egyptian god Set; the thigh is the "phallic leg of Set", symbolising virility. Hippos are cantankerous animals that belligerently defend their territory, in the case of males; and their offspring, in the case of females. As one hippo moves away, we can guess that the other is the victor of this battle. During the day, they remain cool by staying in the water or mud; reproduction and childbirth both occur in water. A wild male hippo was caught, castrated and released again, but it cost about US$50,000. [85] Incidents of hippo cannibalism have been documented, but this is believed to be the behaviour of distressed or sick hippos. Archaeological evidence exists of its presence in the Levant, dating to less than 3,000 years ago. The hippo is among the most dangerous animals in the world due to its highly aggressive and unpredictable nature. Hippos are huge, docile mammals. Hippos are graceful in water, good swimmers, and can hold their breath underwater for up to five minutes. When the flood waters recede different pods of hippo are often forced to share territory which results in an uneasy alliance, with males constantly fighting over territory. [74], Adult hippos move at speeds up to 8 km/h (5 mph) in water; typically resurfacing to breathe every three to five minutes. [18], While the fossil record of hippos is still poorly understood, the two modern genera, Hippopotamus and Choeropsis (sometimes Hexaprotodon), may have diverged as far back as 8 million years ago. [8]:129[99][100], Like many zoo animals, hippos were traditionally displayed in concrete exhibits. [34]:259 The testes of the males descend only partially and a scrotum is not present. This angle shows us just how bulky those hippo bodies are. They inhibit the growth of disease-causing bacteria, and their light absorption peaks in the ultraviolet range, creating a sunscreen effect. [58] As of 2020, there were no plans by the local government on managing the population, but further studies on their effect on the habitat have been initiated. [8]:4, Hippos mark their territory by defecation. When hippos yawn, as the ones pictured here seem to be doing, it isn’t a good sign. Somewhat bizarrely, at least from a Darwinian perspective, after a necking battle, the males will often caress one another with their necks (which is sometimes misinterpreted as fighting) and then have sex with each other [34]:259, 263 The hippo is considered to be a pseudoruminant; it has a complex three-chambered stomach but does not "chew cud". While hippos rest near each other in the water, grazing is a solitary activity and hippos are not territorial on land. Like the hippo spectator seen here, humans are also entertained by the regular matches – as long as they don’t get too close. Hippos are known to be very aggressive towards both of these types of animals. [77] Lions occasionally prey on adults at Gorongosa National Park and calves are sometimes taken at Virunga. The reason they huddle close together is unknown. We’d be trying to get some distance from that nasty-looking maw as well. The lethal daggers at the front of their mouths are there for one reason only: for use in battle, usually against one another. [85] This is because of the female's oestrous cycle; as with most large mammals, male hippo spermatozoa is active year-round. [35] The bite force of an adult female hippo has been measured as 8,100 newtons (1,800 lbf). [105] The Ijaw people of the Niger Delta wore masks of aquatic animals like the hippo when practicing their water spirit cults[106] and hippo ivory was used in the divination rituals of the Yoruba. [19] Isolated members of Malagasy hippos may have survived in remote pockets; in 1976, villagers described a living animal called the kilopilopitsofy, which may have been a Malagasy hippo. They even inspired a popular board game, Hungry Hungry Hippos. [116] The "Happy Hippos" characters were created in 1987 by the French designer André Roche to be hidden in the "Kinder Surprise egg" of the Italian chocolate company Ferrero SpA. Or are they? [83] Although hippos lie close to each other, they do not seem to form social bonds except between mothers and daughters, and they are not social animals. The Malagasy hippos were smaller than the modern hippo, likely through the process of insular dwarfism. [8]:3 The eyes, ears, and nostrils of hippos are placed high on the roof of their skulls. [8]:60–61 After becoming pregnant, a female hippo will typically not begin ovulation again for 17 months. Aggregations of crocodiles have also been seen to dispatch still-living male hippos that have been previously injured in mating battles with other males. [65] The "American Hippo Bill" fell just short of being passed. When hippos emerge from the water to graze, they do so individually. [31] Despite being semiaquatic and having webbed feet, an adult hippo is not a particularly good swimmer nor can it float. [12], One branch would evolve into cetaceans, possibly beginning about 52 million years ago, with the protowhale Pakicetus and other early whale ancestors collectively known as Archaeoceti, which eventually underwent aquatic adaptation into the completely aquatic cetaceans. Even crocodiles working together will struggle to take down one of these mighty creatures. Hippos are incredibly aggressive and territorial, especially towards crocodiles and alligators. For example, the Disney film Fantasia featured a ballerina hippo dancing to the opera La Gioconda,[50] Hanna-Barbera created Peter Potamus. A few hippos that were brought to Colombia for a zoo have been running wild for over 25 years. [63][64] The chief collaborators and proponents of Broussard's bill were Major Frederick Russell Burnham and Captain Fritz Duquesne. These animals are semi-aquatic, after all, so getting wet is definitely not a deterrent. While hippopotamid species spread across Asia and Europe, no hippos have ever been discovered in the Americas, although various anthracothere genera emigrated into North America during the early Oligocene. However, one of the most dangerous animals on the continent is actually not even a meat eater but a herbivore. Alternative methods have been considered, but they are unproven, or difficult and expensive. [55], In the late 1980s, Pablo Escobar kept four hippos in a private menagerie at his residence in Hacienda Nápoles, 100 kilometres (62 mi) east of Medellín, Colombia, after buying them in New Orleans. This is an example of mutualism, in which the hippo benefits from the cleaning while the fish receive food. Despite their cranky dispositions, hippos tend to live in large groups. Even other dangerous animals including crocodiles and alligators won’t mess with them. Hippos are dangerous creatures and are the animals responsible for more human deaths than other animals, even crocodiles. [17] Merycopotamus, Libycosaurus and Hippopotamidae can be considered to form a clade, with Libycosaurus being more closely related to hippos. [34]:260 When hippos become over-populated or a habitat is reduced, males sometimes attempt infanticide, but this behaviour is not common under normal conditions. [88][85], The earliest evidence of human interaction with hippos comes from butchery cut marks on hippo bones at Bouri Formation dated around 160,000 years ago. Invooboo! [86] Hippos will also express threat and alarm with exhalations. Those pointy teeth sticking out like giant thorns from the hippos’ mouths are not what we’re accustomed to seeing on animals that eat vegetation. Luckily, the Serengeti National Park is still home to numerous hippos and is a great place to witness thrilling interactions like this one. Range map of the hippopotamus. Why Can’t Hippos Swim And Other Fascinating Animal Facts of the Week July 3, 2020 Leave a Comment Even if you’re as obsessed with animals as we are, you often hear new facts you haven’t heard before, the kind which make you reappraise what you thought you knew. [102] The exhibit was so popular, the hippos became the logo of the Toledo Zoo. [8]:64, Mother hippos are very protective of their young and may keep others at a distance. [56][57] In 2009, two adults and one calf left their herd and, after attacking humans and killing cattle, one of the adults (called "Pepe") was killed by hunters under authorisation of the local authorities. [53] However, as of 2016, the Virunga hippo population appears to have increased, possibly due to greater enforcement and cooperation between fishermen and park authorities. [78] Crocodiles are frequent targets of hippo aggression, probably because they often inhabit the same riparian habitats; crocodiles may be either aggressively displaced or killed by hippos. [31] Weaning starts between six and eight months after birth, and most calves are fully weaned after a year. [54] The sale of hippo meat is illegal, but black-market sales are difficult for Virunga National Park officers to track. "[94], The hippo is considered to be extremely aggressive and has frequently been reported charging and attacking boats. Normally, these battles don’t end in death, but when one opponent gives up in the face of the other’s obvious superiority. They grow to between 10.8 and 16.5 feet (3.3 to 5 meters) long and up to 5.2 feet (1.6 m) tall at the shoulder. [8]:84, Hippo defecation creates allochthonous deposits of organic matter along the river beds. ", "Goodbye, Donna: World's oldest hippo in captivity dies at 61", "Bertha, the world's 'oldest' hippo, dies at 65", "The Eemian mammal fauna of central Europe", "The Hippopotamus Going - Extinction of the huge species at hand", "Hippos Butchered by the Hundreds in Congo Wildlife Park", "After a Long Demise Due to Poaching, Virunga's Hippos Climbing Back", "Zoo Gone Wild: After Escobar, Colombia Faces His Hippos", "Could Pablo Escobar's Escaped Hippos Help the Environment? Rose, M. (2010). [37][38] All hippos, even those with different diets, secrete the pigments, so it does not appear that food is the source of the pigments. [51][52] Reasons for poaching include the belief that hippos are harmful to society, as well as financial gain. Bull Hippos can initiate attack if they find another Hippopotamus amphibius was widespread in North Africa and Europe during the Eemian[45] and late Pleistocene until about 30,000 years ago. And while we don’t know for sure, we imagine that this will not be the last fight for either of them. By 2007, the animals had multiplied to 16 and had taken to roaming the area for food in the nearby Magdalena River. It’s just lucky for hippos that their protective hides are 6 inches thick. Two hippos fighting each other in Ngorongoro crater. This is because Hippos are extremely large, highly territorial and aggressive. There are other reports of meat-eating, and even cannibalism and predation. The three of them often share the same bodies of water. In the 1980s, zoo exhibits increasingly reflected native habitats. When she died in 2017, her age was estimated to be 65.[44]. Hippos are one of the big five animals. [1] Proper habitat requires enough water to submerge in and grass nearby. The function of these is unknown. [34]:273[8]:118 However, due to their aggression and size, adult hippos are not usually preyed upon by other animals. Several lines of evidence, first from blood proteins, then from molecular systematics[12] and DNA [80][81][82], Studying the interaction of males and females has long been complicated because hippos are not sexually dimorphic; thus females and young males are almost indistinguishable in the field. Hippos have been known to kill people, even though they're vegetarians. [8]:50 Younger bachelors are allowed in a male's stretch, as long as they behave submissively toward the male. A study of hippo reproductive behaviour in Uganda showed that peak conceptions occurred during the end of the wet season in the summer, and peak births occurred toward the beginning of the wet season in late winter. Cannibalism may be a major human taboo, but it's surprisingly common in the animal kingdom. [68] A 2015 study concluded that hippo dung provides nutrients from terrestrial material for fish and aquatic invertebrates,[71] while a 2018 study found that their dung can be toxic to aquatic life in large quantities, due to absorption of dissolved oxygen in water bodies. It is rarely found in deep water; when it is, the animal moves by porpoise-like leaps from the bottom. Baring razor-sharp teeth, these massive creatures lock together in a fight, caught on film in this sequence of incredible images by wildlife photographer Sam D’Cruz. This old male is king of this stretch of the [107] The Behemoth from the Book of Job, 40:15–24 is thought to be based on a hippo. They were deemed too difficult to seize and move after Escobar's death, and hence left on the untended estate. In general, the scars that mark a hippo’s hide are souvenirs from its many fights. The incisors can reach 40 cm (1 ft 4 in), while the canines reach up to 50 cm (1 ft 8 in). In addition, the penis retracts into the body when not erect. (1,600 to 4,500 kg), according to the San Diego Zoo. [63], Hippos differ from all other large land mammals, being of semiaquatic habits, and spending their days in lakes and rivers. [68] Hippos are born with sterile intestines, and require bacteria obtained from their mothers' feces to digest vegetation. In addition, the hippo keeps those impressive choppers sharp by rubbing them together. While depositing the faeces, hippos spin their tails to distribute their excrement over a greater area. Huge collection, amazing choice, 100+ million high quality, affordable RF and RM images. Further, some taxonomists group hippos and anthracotheres in the superfamily Anthracotheroidea. Sometimes, the subfamily Hippopotaminae is used. She lived at the Mesker Park Zoo in Evansville, Indiana in the US[41][42] until her death in 2012 at the age of 61. Hippos are aggressive creatures, and they have very sharp teeth. They suckle on land when the mother leaves the water. The average female weighs around 3,000 lbs. In May 2006, the hippo was identified as a vulnerable species on the IUCN Red List drawn up by the International Union for Conservation of Nature (IUCN), with an estimated population of between 125,000 and 150,000 hippos, a decline of between 7% and 20% since the IUCN's 1996 study. Dominant hippo bulls usually preside over a territory that includes a pod of females. Hippos inhabit rivers, lakes, and mangrove swamps, where territorial males preside over a stretch of river and groups of five to thirty females and young hippos. The pygmy hippopotamus belongs to a different genus in Hippopotamidae, either Choeropsis or Hexaprotodon. Very territorial vegetarians. In one 2014 case in Niger, a boat was capsized by a hippo and 13 people were killed. [4][5][6] In English, the plural is "hippopotamuses", but "hippopotami" is also used.[7]. After begging and pleading, the hippos were finally allowed to live in the water on the conditions that they would eat grass instead of fish and would fling their dung so that it can be inspected for fish bones. A rough evolutionary lineage can be traced from Eocene and Oligocene species: Anthracotherium and Elomeryx to the Miocene species Merycopotamus and Libycosaurus and the very latest anthracotheres in the Pliocene. Hippos are very rotund animals and are the third largest living land mammals, after elephants and white rhinos, according to Animal Planet. This secretion is initially colourless and turns red-orange within minutes, eventually becoming brown. [30], Hippos have barrel-shaped bodies with short legs and long muzzles. This page was last edited on 11 December 2020, at 09:19. Lions, leopards, crocodiles and deadly snakes all spring to mind. Yes, he is better than a lion – he is a hippopotamus. The secretion is sometimes referred to as "blood sweat", but is neither blood nor sweat. In the case of hippos, they usually had a pool of water and patch of grass. Hippo tusks are, however, made of rhino keratin, heavier than ivory. [39] The secretion does help regulate the body temperature of the hippo and acts as an antibiotic. [8]:82–83, Hippos appear to communicate vocally, through grunts and bellows, and they may practice echolocation, but the purpose of these vocalisations is currently unknown. On occasion, young hippos get caught in the middle of violent clashes between adults and can be bitten or crushed, even by their own parent. [84] "Yawning" serves as a threat display. The young often rest on their mothers' backs when the water is too deep for them, and they swim under water to suckle. Hippos are cantankerous animals that belligerently defend their territory, in the case of males; and their offspring, in the case of females. Five subspecies of hippos have been described based on morphological differences in their skulls and geographical differences:[8]:3, The suggested subspecies were never widely used or validated by field biologists; the described morphological differences were small enough that they could have resulted from simple variation in nonrepresentative samples. (1,400 kilograms), while males weigh 3,500 to 9,920 lbs. [93] They would chant their chief: "Een-gonyama Gonyama! Hippopotamus is the type genus of the family Hippopotamidae. [40], A hippo's lifespan is typically 40–50 years. By contrast, its subcutaneous fat layer is thin. In areas undisturbed by people, hippos lie on the shore in the morning sun. And you would not want to get stuck under one; at up to 2,750kg they can crush a human to death. [97], Hippos have long been popular zoo animals. [8]:39 Hippopotamidae are classified along with other even-toed ungulates in the order Artiodactyla. Invooboo!" Heading for the water is normally a good plan for hippos trying to evade an attack, except perhaps when it’s against another hippo. Reports of the slaughter of the last hippo in Natal Province were made at the end of the 19th century. [8]:4 The process of surfacing and breathing is subconscious: a hippo sleeping underwater will rise and breathe without waking up. 39 interesting facts about hippos. [90], The hippo was also known to the Greeks and Romans. The hippos part briefly, but we can be sure it isn’t for long. No need to register, buy now! Hippos are one of the easiest animals to find on an African safari. However, there’s nothing funny at all about coming up against an angry hippo. The largest pods can contain over 100 hippos. [38] Nevertheless, this natural sunscreen cannot prevent the animal's skin from cracking if it stays out of water too long. [109], Ever since Obaysch inspired the "Hippopotamus Polka", hippos have been popular animals in Western culture for their rotund appearance that many consider comical. The first record of hippos on captivity for display are dated to 3500 BC, in Hierakonpolis, Egypt. [15] The common ancestor of hippos and whales branched off from Ruminantia and the rest of the even-toed ungulates; the cetacean and hippo lineages split soon afterwards. These chunky creatures come in third place when it comes to ranking the world’s biggest land animals, with only white rhinos and elephants beating them out. [115] and the Madagascar films feature a hippo named Gloria. Unfortunately, such skirmishes aside, the general hippo population is dwindling owing to a loss of habitat plus the actions of poachers who value the animals’ ivory teeth. Scribol has built a large and loyal audience that now numbers 20MM visitors per month, making it From 7.5 to 1.8 million years ago, an ancestor to the modern hippo, Archaeopotamus, lived in Africa and the Middle East. [72][73] Because of their size and their habit of taking the same paths to feed, hippos can have a significant impact on the land across which they walk, both by keeping the land clear of vegetation and depressing the ground. Here’s a closer view of the two combatants. For example, the Toledo Zoo Hippoquarium features a 360,000-US-gallon (1,400,000 l) pool. [67], Like most herbivores, hippos consume other plants if presented with them, but their diet in nature consists almost entirely of grass, with only minimal consumption of aquatic plants. An adult female hippo’s bite has been shown to have the pressure of 8,100 newtons. They are threatened by habitat loss and poaching for their meat and ivory canine teeth. Still, as you can see from these photographs, that might take a while. But the hippo is more closely related to the pig than the horse. [8]:49 Hippos are territorial only in water, where a male presides over a small stretch of river, on average 250 m (270 yd) in length, and containing 10 females. [31] The canines and incisors are used for combat and play no role in feeding. [92] Zulu warriors preferred to be as brave as a hippo, since even lions were not considered to match its courage. [62][63] Broussard argued that the hippos would eat the invasive water hyacinth that was clogging the rivers and also produce meat to help solve the American meat crisis. For other inquiries, Contact Us. Hippopotamidae are sometimes known as hippopotamids. [88], Mating occurs in the water, with the female submerged for most of the encounter,[8]:63 her head emerging periodically to draw breath. [13][15] This hypothesised ancestral group likely split into two branches around 54 million years ago. [51] The poachers are believed to be Mai-Mai rebels, poorly paid Congolese soldiers, and local militia groups. The Latin word "hippopotamus" is derived from the ancient Greek ἱπποπόταμος, hippopótamos, from ἵππος, híppos, "horse", and ποταμός, potamós, "river", meaning "horse of the river". [69] On occasion, hippos have been filmed eating carrion, usually near the water. Hippos are far less aggressive than a Rhinoceros, but they are easily agitated in contrast with the Rhino. A hippo closes its nostrils when it submerges into the water. For mothers and their young, these “schools,” as they’re called, offer some safety from predators that may attack the calves. Neither H. a. tschadensis nor H. a. constrictus has been tested. And as you can see from these images, the hippopotamus is as menacing as any carnivore. [34]:260 The skin is 6 cm (2 in) thick,[31] providing it great protection against conspecifics and predators. The incisors may extend to 1.3 feet in length, while the canines can measure an incredible 1.6 feet. The hippopotamus (/ˌhɪpəˈpɒtəməs/ HIP-ə-POT-ə-məs;[3] Hippopotamus amphibius), also called the hippo, common hippopotamus or river hippopotamus, is a large, mostly herbivorous, semiaquatic mammal and ungulate native to sub-Saharan Africa. [34]:264 Hippos mostly live in freshwater habitats, however populations in West Africa mostly inhabit estuarine waters and may even be found at sea. Spray flies as the hippos clash once more. [113][114], Hippos have also been popular cartoon characters, where their rotund frames are used for humorous effect. It is one of only two extant species in the family Hippopotamidae, the other being the pygmy hippopotamus (Choeropsis liberiensis or Hexaprotodon liberiensis). This allows these organs to remain above the surface while the rest of the body submerges. These deposits have an unclear ecological function. However, calves are occasionally left in nurseries which are guarded by one or a few adults. Crocodile vs Hippo Wild Animals Fighting, Hippo, Rhino, Crocodile . Fights between rivals are a common occurrence in the Serengeti, a terrain that – even during waterless periods – is home to pools big enough for hippos to congregate in. Pliny the Elder writes that, in his time, the best location in Egypt for capturing this animal was in the Saite nome;[48] the animal could still be found along the Damietta branch after the Arab Conquest in 639. Hippos are one of the noisiest animals in Africa: some hippo vocalizations have been measured at 115 Among the extant African megafauna, behind the two African elephant species, they average smaller than the white rhinoceros but are larger by body mass than the black rhinoceros and the giraffe. All three species became extinct before the last glaciation. The Rhino has inadequate space to sprint and hammer the Hippo, his choice is to wipe his paws. Hippos VS Crocodiles Fighting - Hippos Save Wildebeest from Crocodiles - Amazing Animals Save Other Animals Thank You for watching ! [17][18], Three species of Malagasy hippopotamus became extinct during the Holocene on Madagascar, one of them within the past 1,000 years. These findings have important conservation implications as hippo populations across the continent are currently threatened by loss of access to fresh water. [95] Small boats can easily be capsized by hippos and passengers can be injured or killed by the animals or drown. They spend four to five hours grazing and can consume 68 kg (150 lb) of grass each night. [1], The hippo population declined most dramatically in the Democratic Republic of the Congo. [51] The decline is attributed to the disruptions caused by the Second Congo War. Despite its stocky shape and short legs, it is capable of running 30 km/h (19 mph) over short distances. Despite their physical resemblance to pigs and other terrestrial even-toed ungulates, the closest living relatives of the Hippopotamidae are cetaceans (whales, dolphins, porpoises, etc. Snackable content that delights, informs and entertains. Calves in nurseries engage in playfights. [52][53] Hippo meat is considered a delicacy in some areas of central Africa and the teeth have become a valued substitute for elephant ivory. In this photograph, we get an even closer view of those magnificent teeth as the two hippos lash out. [59] Because of the fast-growing population, conservationists have recommended that a management plan needs to be rapidly developed. We can totally understand why the hippo on the right is backing away here. [89] Later rock paintings and engravings showing hippos being hunted have been found in the mountains of the central Sahara dated 4,000–5,000 years ago near Djanet in the Tassili n'Ajjer Mountains. [34] : 260 When hippos become over-populated or a habitat is reduced, males sometimes attempt infanticide , but this behaviour is not common under normal conditions. A mother typically gives birth to only one calf, although twins also occur. [31] Their skeletal structures are graviportal,[8]:8 adapted to carrying their enormous weight, and their specific gravity allows them to sink and move along the bottom of a river. Young males can live in the herds providing they pose no threat to the main bull. Hippos have the unique ability to hold their heads partially above the water and send out a cry that travels through both water and air; individuals respond above and under water. Length and sharpness of the teeth not off-putting enough for you? The 2 instances shown in this video are perfect examples.
