The pygmy hippopotamus is a species of hippopotamus that lives in the rivers and swamps of West Africa. It is the smallest species of hippo, with males typically weighing around 300 pounds (136 kg) and females weighing up to 400 pounds (181 kg). They are also the most threatened species of hippopotamus due to habitat destruction and hunting for meat and ivory.
