The pygmy hippopotamus (Choeropsis liberiensis) is one of two extant species of hippo. This rather adorable mammal inhabits forested swamps across West Africa but their population has declined in recent years due to drastic habitat loss. This pygmy species is very similar in shape to its larger relative, the common hippopotamus (Hippopotamus amphibius), and they both share a semi-aquatic, herbivorous lifestyle. However, the pygmy hippo weighs between 180 to 275 kilograms whereas the common hippo can reach an extraordinary 1,500 kg!
Pygmy hippos are nocturnal mammals thus making them quite secretive creatures. Their diet consists of various grasses, fruits, ferns and other plants found in their forest habitat. Pygmy hippos have a dark brown-black skin colouration that is darker than the pinkish-grey hue of common hippos.
This mammal is a cute and unique species but unfortunately they are classified as endangered by the IUCN Red List and face a range of human dangers that threaten their survival. The greatest threat is habitat loss; unsustainable logging of their forested habitat is causing the population of pygmy hippos to become fragmented. Subsequently, each divided population has less genetic diversity, shrinking the species’ gene pool and due to their elusive nature, their wild population size is uncertain. The pygmy hippopotamus is not well known and their endangered status even less so, therefore we need to help raise awareness for this species and encourage sustainable logging throughout West Africa.
