[8][11], A distinct subspecies of pygmy hippopotamus existed in Nigeria until at least the 20th century, though the validity of this has been questioned. [10] The gestation period ranges from 190–210 days, and usually a single young is born, though twins are known to occur. [1][23], Pygmy hippos consort for mating, but the duration of the relationship is unknown. How often this occurs is unknown. at birth and are able to swim almost immediately. Saotherium and Choeropsis are significantly more basal than Hippopotamus and Hexaprotodon, and thus more closely resemble the ancestral species of hippos. Pygmy hippo water is adapted to spend time, but aquatic far less than hippo quiggie hippo teeth are different: it only has one pair of incisors, while hippo has two or three. The effects of West African citizen strife on the pygmy hippopotamus are unknown but are unlikely to be positive. The small hippopotamides of most species have also disappeared into the late Pleistocene or early Holocene in the Mediterranean. Save my name, email, and website in this browser for the next time I comment. Hippopotamus will often travel up to six miles from their watering hole to eat something. At birth the calf weighs between 4.5 and 6.2 kgs (9.9 - 13.7 lbs) and they can swim almost immediately. [13] The Hippopotamidae are believed to have evolved in Africa, and while at one point the species spread across Asia and Europe, no hippopotami have ever been discovered in the Americas. They do not eat aquatic vegetation to a significant extent and rarely eat grass because it is uncommon in the thick forests they inhabit. The Pygmy Hippo is the smaller species, standing about waist-high to an adult human the common/river hippopotamus is world's third largest and heaviest land animals, weighing up to about 4,000 kg. [17][18], This hypothesized ancestor likely split into two branches about six million years later. Hippos and whales shared a common semi-aquatic ancestor that branched off from other artiodactyls around 60 mya. The pygmy hippo is less aquatic than its larger relative, although, when pursued, it hides in water. They have grey-brown skin, small ears and sturdy legs with fourtoed feet, and can usually be found near rivers, where they spend most of their time wallowing and sleeping. A rare nocturnal forest creature, the pygmy hippopotamus is a difficult animal to study in the wild. Most of the Pygmy Hippo diet consists of ferns, wide-ranging plants, and fruits that fall on the forest floor. They actually move along the bottom of the water in a slow gallop. The biggest threat to the remaining pygmy hippopotamus population in the wild is the loss of habitat. The mother returns to the hiding place about three times a day and calls the calf to suck. Pygmy hippos were successfully introduced to Europe in 1911. Hippo Diet – What Do Hippos Eat? Groups of 10-30 hippos live together with one dominant male. They will rest in the same spot for several days in a row, before moving to a new spot. Adult pygmy hippos reach 70-80 cm in height and are believed to have diverged from the common hippo over 10 million years ago. Pygmies are much smaller in size – weighing just a fifth of their cousin's weight. They have large teeth and teeth that they use to fight threats, including humans. [9][22], The skin is greenish-black or brown, shading to a creamy gray on the lower body. Hippo Blood Sweat – What Color is the Sweat of a Hippo? [8][13], Several species of small hippopotamids have also become extinct in the Mediterranean in the late Pleistocene or early Holocene. A sister species of the pygmy hippopotamus may have been the little-studied Malagasy pygmy hippopotamus (Hexaprotodon madagascariensis or Hippopotamus madagascariensis), one of three recently extinct species from Madagascar. The Pygmy Hippopotamus is closely related to Africa's other Hippopotamus species, which is the Common Hippopotamus but is much smaller in size weighing around a [1][8][9][10] Samuel G. Morton initially classified the animal as Hippopotamus minor, but later determined it was distinct enough to warrant its own genus, and labeled it Choeropsis. Hippos can even sleep underwater, using a reflex that allows them to wake up, breathe, and sink back without waking. The newborn hippo lives alone as the mother forages, visiting to suckle the baby 3 times a day. The Nigerian pygmy hippopotamus was never studied in the wild and never captured. Though these species are sometimes known as "pygmy hippopotami" they are not believed to be closely related to C. liberiensis. 19. It traces the tail with its tail firmly in place while leaving the rectum to spread its feces further. [14] All agree that the modern pygmy hippopotamus, be it H. liberiensis or C. liberiensis, is the only extant member of its genus. In certain conditions of zoo species survival more certain than the survival of wild species, the pygmy hippo survives 42 to 55 years longer than the wild. The closest non-hippo relative to the hippo species is the whale. All research and all zoo specimens are the Liberian subspecies. [10], The first pygmy hippo was brought to Europe in 1873 after being captured in Sierra Leone by a member of the British Colonial Service but died shortly after arrival. The pygmy hippo, however, is only half as tall as the hippopotamus and weighs less than 1/4 as much as its larger cousin. Pygmy Hippopotamus are native to western Africa, found mainly in the rivers and swamps of Liberia but also in Sierra Leone, Guinea, and the Ivory Coast. [21] Their lifespan in captivity ranges from 30 to 55 years, though it is unlikely that they live this long in the wild. A Pygmy Hippopotamus, or a pygmy hippo, is a kind of nocturnal species closely attached to common Hippopotamus we see. Pygmy hippos have an abnormal emission similar to that of ordinary hippos, which have a pinkish color on their body and are sometimes described as “blood sweat” although this emission is not sweated or blood. Source: Live Science. Field studies estimate that the male pygmy hippos have a range of 1.5 km2 (৪60০ acres), while a female ranges from 0.4 to 0.6 km2 (99–148 acres). Less than one-sixth the size of the common hippo , pygmy hippos are only about 5 feet long, 3 feet tall, and 500 to 600 pounds. [9], The common hippopotamus gives birth and mates only in the water, but pygmy hippos mate and give birth on both land and water.

The skin of hippos dries out quickly and cracks, which is why both species spend so much time in water. It is probably extinct. [10] The youngest reported age for giving birth is a pygmy hippo in the Zoo Basel, Switzerland which bore a calf at three years and three months. Men, called bulls, have a larger area than cows, and both mark their homes with their bows. On the 9th of May, Pygmy hippopotamus Venus gave birth to a healthy calf after a gestation period of 6 months! Some adult males (called bulls) can weigh up to nearly three tons, but the average range is between 3,300 and 7,050 pounds (1,500 and 3,200 kg). Recent population estimates indicate that wild areas may have less than 3,000 pygmy hippos. A group of hippopotami is known as a herd or a bloat.[4]. liberiensis. The calves weigh 4.5 to 6.2kg (9.9 to 13.6 lb.) [1], Pygmy hippos are among the species illegally hunted for food in Liberia. The wide variety of plants pygmy hippos have been observed eating suggests that they will eat any plants available. The legs of the pygmy hippos are narrower, but the toes are more spread out and have less webbing to help move them to the forest floor. They are large mammal native to the swamps and forest of the Western Africa. Morton first described the species in 1843. The bulk of a pygmy hippo's diet consists of ferns, broad-leaved plants and fruits that have fallen to the forest floor. A rare nocturnal forest animal, pygmy hippopotamus is a difficult animal to study in the wild. Want to know the key differences between Pygmy hippos and their large cousins? The pygmy hippo is reclusive and nocturnal. While some local populations are aware that the species once existed, its history in the region is poorly documented. The common hippopotamus only gives birth and mates in water, but pygmy hippos mate and give birth on both land and water. Sometimes the sub-family Hippopotaminae is used. Where common hippos are widely distributed, highly visible, and hardly any of the most dangerous large animals in Africa have ever seen the pygmy hippo in the wild. Pygmy hippos are endangered with less than 3,000 left in the wild. [9], The evolution of the pygmy hippopotamus is most often studied in the context of its larger cousin. share. They have a graviportalskeleton, with four stubby legs and four toes on each foot, supporting a portly frame. Their skin is several centimeters thick that is very similar to ordinary hippos with a thin epidermis on the dermis. Pygmy hippos are actually more suited to land than large hippos. Pygmy hippos are shy, lonely and nocturnal, living mainly in forests and wetlands. [11], This assertion was widely accepted,[1][8][9][10] until Boisserie asserted in 2005 that the pygmy hippopotamus was not a member of Hexaprotodon, after a thorough examination of the phylogeny of Hippopotamidae. The origins and nasal texts of the pygmy hippo are rarely pronounced, an adaptation of spending less time in deep water (where the pronounced orbit and nostrils help the common hippo to breathe and see). Much of its behavior is more similar to that of a tapir, though this is an effect of convergent evolution. Kenyapotamus is known only through fragmentary fossils, but was similar in size to C. The pygmy hippo spends about six hours a day foraging for food. Pygmy hippos are primarily threatened by habitat loss, as forests are logged and converted to farmland, and poaching, bushmeat, natural predators and war victims are also occurring. Like the normal hippopotamus, pygmy emerges from the water during the evening to eat hippos. The subspecies is named after I. R. P. Heslop, who claimed in 1945 to have shot a pygmy hippo in the Niger Delta region and collected several skulls. Nomenclature of the pygmy hippopotamus reflects that of the hippopotamus. For example, the pygmy hippopotamus is a distinct species, separate from the common hippopotamus. Pygmy hippo herbs, found in the forest, feed on fern, wide-leaved trees, grasses and fruits. How many pygmy hippopotamus are there in the world? The gestation period lasts from 12-20 days and is usually reported as having given birth to a single young person, although twins are born. They grow to The plural form is pygmy hippopotami (hippopotamuses is also accepted as a plural form by the OED, or pygmy hippos for short). These species, though comparable in size to the pygmy hippopotamus, are considered dwarf hippopotamuses, rather than pygmies. [25] Their lifespan in captivity ranges from 30 to 55 years, though they are less likely to survive this long in the wild. Lifestyle: Lives alone in swamps, streams and dense forest. The ear and nose tubes of the pygmy hippos have strong muscular valves for submersion, and the physiology of the skin is dependent on the availability of water. They are likely descended from a full-sized species of European hippopotamus, and reached their small size through the evolutionary process of insular dwarfism which is common on islands; the ancestors of pygmy hippopotami were also small and thus there was never a dwarfing process. The skin of the hippos dries quickly and gets cracked, which is why both species spend so much time in the water. While the pygmy hippopotamus is semi-aquatic, they have fewer webbed toes to aid them in moving effectively on land. Required fields are marked *. Pygmy Hippos: Pygmy hippos look much like other hippopotamuses except for their size. The pygmy hippopotamus has a sleeker body and narrower mouth and spends much less time in the water than the common hippopotamus. Members of Hippopotamidae are sometimes known as hippopotamids. The behavior of pygmy hippo differs greatly from hippo. C. madagascariensis was the same size as C. liberiensis and shared its terrestrial behavior, inhabiting the forested highlands of Madagascar, rather than open rivers. Starting 7.5 to 1.8 mya the Archaeopotamus, likely ancestors to the genus Hippopotamus and Hexaprotodon, lived in Africa and the Middle East. Pygmy hippos are weaned from six to eight months of age; When they leave their mother for grass before breastfeeding, they do not come with them, but they hide in the water. Introduced to the zoo in the early twentieth century, they breed well in captivity and extensive research has emerged from the zoo specimens. Hippos are very rotund animals and are the third largest living land mammals, after elephants and white rhinos, according to Animal Planet. The young pygmy hippos can swim almost immediately. [9], The skeleton of C. liberiensis is more gracile than that of the common hippopotamus, meaning their bones are proportionally thinner. As forests shrink, the populations become more fragmented, leading to less genetic diversity in the potential mating pool. Population: Only around 3000 in a few countries in West Africa. A single calf is born at a birth weight of 14 lbs.
