Scientific Name and Classification:
The scientific name of the Pygmy Hippopotamus is Hexaprotodon liberiensis. They are also commonly known as the Dwarf Hippopotamus or the Pygmy Hippo. They are classified under the family Hippopotamidae, which also includes the common hippopotamus (Hippopotamus amphibius). There is only one known species of Pygmy Hippopotamus.
The Pygmy Hippopotamus is a semi-aquatic mammal and is the smallest of the two extant species of hippopotamids. They are found only in the rainforests of West Africa.
The Pygmy Hippopotamus was first described in 1849 by British explorer and naturalist John Edward Gray. They were initially thought to be a juvenile form of the common hippopotamus, but further research revealed that they were, in fact, a distinct species.
Evolution and Origins:
The Pygmy Hippopotamus is believed to have evolved from a common ancestor with the common hippopotamus around 10 million years ago. They are thought to have diverged from the common hippopotamus around 7 million years ago, during the late Miocene period. The exact reason for the evolution of the Pygmy Hippopotamus is still unknown, but it is believed that their smaller size and adaptations to the dense rainforest environment allowed them to survive while their larger counterparts died out in this habitat.
The Pygmy Hippopotamus is significantly smaller than the common hippopotamus, measuring around 1.2 to 1.5 meters in length and 75 to 100 centimeters in height at the shoulder. They weigh between 180 and 275 kilograms, with males being slightly larger than females. They have a stocky, barrel-shaped body, short legs, and a broad, rounded head with small ears and eyes. Their skin is thick and hairless, with a grey-brown coloration that provides excellent camouflage in the rainforest environment.
The Pygmy Hippopotamus is a solitary and territorial animal, with individuals typically occupying a home range of around 2-3 hectares. They are most active at night and spend their days resting in the shade of dense vegetation or wallowing in mud pools to regulate their body temperature.
Anatomy and Appearance:
The Pygmy Hippopotamus has a unique anatomy that has evolved to suit their rainforest habitat. They have shorter, more muscular legs than the common hippopotamus, which enables them to navigate through the dense underbrush of the rainforest floor. Their eyes and ears are also positioned higher on their heads than those of the common hippopotamus, allowing them to navigate through the dense vegetation more easily. Additionally, they have a smaller, more pointed snout that helps them forage for food in narrow spaces.
Distribution and Habitat:
The Pygmy Hippopotamus is native to the rainforests of West Africa, primarily found in Liberia, Sierra Leone, Guinea, and the Ivory Coast. They are typically found in dense, lowland rainforest areas near rivers, streams, or swamps, where they can access water for drinking and bathing.
Population - How Many Are Left?:
The Pygmy Hippopotamus is considered to be a critically endangered species, with the current population estimated to be less than 3,000 individuals. Their numbers have been severely impacted by habitat loss due to deforestation, hunting for their meat and ivory tusks, and human encroachment on their remaining habitat.
Size and Weight:
The Pygmy Hippopotamus is significantly smaller than its larger cousin, the common hippopotamus. They measure around 1.2 to 1.5 meters in length and 75 to 100 centimeters in height at the shoulder. They weigh between 180 and 275 kilograms, with males being slightly larger than females.
Behavior and Lifestyle:
The Pygmy Hippopotamus is a solitary and territorial animal, with individuals typically occupying a home range of around 2-3 hectares. They are most active at night and spend their days resting in the shade of dense vegetation or wallowing in mud pools to regulate their body temperature. They are known to be shy and elusive, and it is rare to see them in the wild.
The Pygmy Hippopotamus reaches sexual maturity at around 3-4 years of age. They typically mate during the rainy season, with females giving birth to a single calf after a gestation period of around 190 to 210 days. The mother will care for the calf for up to a year, after which it will become independent.
The Pygmy Hippopotamus has a lifespan of around 30-40 years in the wild, although they have been known to live for up to 50 years in captivity.
Diet and Prey:
The Pygmy Hippopotamus is primarily herbivorous, feeding on a variety of plants, including leaves, fruits, and bark. They are known to be selective feeders, and their diet varies depending on the season and availability of food. They have been observed feeding on over 60 species of plants.
Predators and Threats:
The Pygmy Hippopotamus is threatened by habitat loss due to deforestation and human encroachment on their remaining habitat. They are also hunted for their meat and ivory tusks. Additionally, they are at risk of predation from large carnivores such as leopards, crocodiles, and humans.
Relationship with Humans:
The Pygmy Hippopotamus has been hunted by humans for centuries, primarily for their meat and ivory tusks. Today, they are protected by law in most countries, and efforts are underway to conserve their remaining habitat and protect them from hunting and poaching. They are also kept in captivity in zoos around the world, where they play an important role in educating the public about the conservation of this unique and endangered species.

Pygmy Hippopotamus are truly a remarkable animal, with their unique appearance, behavior, and ecology. Their small size, elusive nature, and unique adaptations have fascinated scientists and researchers for years, leading to extensive research and conservation efforts.
Despite their small size, Pygmy Hippos are powerful and agile animals that can move quickly through their forested habitats. They are herbivores that feed mainly on leaves, fruits, and grasses, and have unique adaptations that allow them to digest tough plant material efficiently. Their social structure is relatively unknown, but they have been observed living in small family groups or alone in the wild.
The Pygmy Hippopotamus is classified as a separate species from the common hippopotamus (Hippopotamus amphibius), with its closest living relative being the now-extinct European hippopotamus (Hippopotamus antiquus). It is believed that the Pygmy Hippopotamus evolved from a common ancestor of the common hippopotamus, adapting to the dense forested environments of West Africa over time.
The Pygmy Hippopotamus has a distinctive appearance, with a smaller size and proportionally longer legs than its larger relative. They are covered in a dense, dark gray or black coat, with a hairless face and small, round ears. Their eyes are set on the sides of their head, allowing for better peripheral vision, and their nostrils can close tightly to keep water out when they are submerged.
Pygmy Hippopotamus are critically endangered, with only an estimated 2,000 to 3,000 individuals left in the wild. Habitat loss due to deforestation and human encroachment, as well as hunting for their meat and ivory tusks, are the main threats to their survival. In addition to conservation efforts to protect their remaining habitat, Pygmy Hippopotamus are also being bred in captivity in zoos around the world as part of breeding and reintroduction programs.
In summary, Pygmy Hippopotamus are a unique and fascinating animal that are facing numerous challenges in the wild. Through education and awareness, as well as conservation and breeding efforts, we can help protect this amazing animal and ensure its survival for generations to come.
