The Hippopotamus, scientifically known as the Hippopotamus amphibius and commonly called the Hippo, is an omnivore mammal native to Sub-Saharan Africa. There are two kinds of Hippos found in the wild: the common Hippo and the pygmy Hippo. They are both aquatic and terrestrial and have webbed feet. Their short legs help them to propel in water and also provide to maintain their balance on land. Contrasting their aggressive temperament, Hippos feed mainly on plants and leaves and often get into a tussle with crocodiles in swamps and lakes. A large herd of Hippos can be found in Tanzania and Zambia. The populations of Hippos are decreasing in the Republic of Congo and the Virunga National Park.

Their diet is mainly herbivorous though they might sometimes feed on aquatic plants. In order to prevent their nose and ears from water, Hippos can close their nostrils and ears. This ability allows Hippos to suckle on land as well as underwater. Hippos spend almost 16 hours every day in water and are regarded as third largest living land animals. They are known to be able to hold their breath for up to five minutes underwater. Hippos prefer to live in shallow waters of rivers as they can easily sleep there when they are half submerged in the river water.

Hippo Interesting Facts

What type of animal is a Hippo?

The Hippopotamus is a semi-aquatic animal that feeds on plants and leaves and is an opportunistic hunter. They lack sweat glands and have thin outer skin, which often gets bruised while fighting. These animals cool themselves by dipping themselves in water and mud. Hippos spend around two-thirds of their time in water. Common Hippos get involved in regular fights, while pygmy Hippos are solitary animals and only socialize during the mating period.

What class of animal does a Hippo belong to?

The Hippopotamus is a land mammal but also can be found submerged in water bodies like lakes and swamps for cooling themselves in the hot weather. Common Hippos often are found in groups of 20-100 while pygmy Hippos prefer leading a solitary life. Common Hippos segregate themselves into smaller groups when there is a scarcity of food. Hippos are also known as Amphibious African ungulate mammal.

How many Hippos are there in the world?

The population of the Hippopotamus has been declining for the last ten years due to habitat loss, pollution of water bodies, and unavailability of food and water resources. Though the IUCN Red List has not listed these amphibious animals as Endangered, the pygmy Hippos are considered to be endangered while the common Hippos are listed as Vulnerable respectively. If the population of these mammals continues to decline in the future, they would shortly become extinct.

Where does a Hippo live?

The common Hippos live with their group in swamps, lakes, and wetlands and are semi-aquatic and semi-terrestrial, while the pygmy Hippos are largely terrestrial. Hippos are freshwater animals and spend 16 hours of their day in the water, keeping their skin moist and their temperature cool in the high heat of Africa. Hippos’ habitat in Western Africa can also be found at seashores and inside the sea in estuarine waters. The process of surfacing and breathing is automatic in Hippos and even a Hippo that is sleeping underwater will automatically rise and breathe without waking.  

What is a Hippo's habitat?

African Hippos are semi-aquatic mammals and are native to sub-Saharan Africa. Hippopotamuses are also hunted by humans for the popularity of their meat and horns. Predators like hyenas, lions, tigers, and cheetahs also consume Hippos. They can be found throughout Africa loitering with their group near water bodies. They can breathe as well as see even when they are submerged in water.

Who do Hippos live with?

African Hippopotamus lives with their own species in the wild while Pygmy Hippos live an isolated life except during the mating period. A group of Hippos is called a bloat, pod, or siege, which includes 20-100 common Hippos that live together. This group includes both male and female Hippos who mate during the breeding season.

How long does a Hippo live?

The Hippopotamus is a large African mammal, sometimes it has a violent and aggressive personality, but mostly it chews on leaves and plants for food. The life expectancy for Hippos is around 40-50 years in the wild. A Hippopotamus can die due to many other reasons like loss of habitat, unavailability of food, water pollution, predation, and hunting by humans. The population of Hippos is decreasing due to these reasons, and they have now been listed as vulnerable mammals by the IUCN Red List.

How do they reproduce?

Male Hippopotamuses submerge the female Hippo in the water forcibly, and they mate in the water. The females only lift their heads for breathing through their nostrils. Even though Hippos are semi-aquatic in nature, they cannot swim but can mate in water. Sometimes Hippos do mate on land which is very rare. The gestation period in Hippos lasts for 240 days, and the female Hippos only give birth to one calf per litter.

What is their conservation status?

The populations of Hippopotamuses in the wild has been declining rapidly, and currently, their status has been listed by the IUCN Red List as Vulnerable to Extinction. The Hippos are now restricted to protected areas where they cannot be hunted down by predators as well as humans for their horns, meat, and teeth, which consist of ivory. Populations of pygmy Hippos are also endangered as they are terrestrial in nature and habitat in forests and where the vegetation is dense.
