According to the BBC
, scientists estimate that as few as 2,000 of the rare, endangered Pygmy hippopotamuses
remain in the forested West African ecosystem, but researchers were able to use motion-sensing cameras to unveil more about these difficult-to-study, secretive nocturnal animals as part of ongoing efforts to save them.
Expanding human development of the pygmy hippo's natural forest habitat poses the biggest threat to the species' survival in the wild, according to the team
The researchers hope the movie project will lead to new discoveries about the elusive animals that will help focus conservation plans
underway in Liberia, Guinea, Côte d’Ivoire and Sierra Leone.
According to the Smithsonian National Zoological Park
and the Ultimate Ungulate website, pygmy hippopotamuses (Hexaprotodon liberiensis
), along with their much larger cousins the Nile or River hippopotamuses
, belong to the Hippopotamidae
family, and both are closely related to peccaries and pigs.
Though pygmy hippos are more terrestrial than Nile hippos, they are good swimmers with similar muscular valves that close and protect their nostrils and ears when they submerge to feed on aquatic plants, according to
the San Diego Zoo.
