On Safari with Nala - Hippos

The video discusses the hippopotamus, its Greek name origin, and its status as the third largest land animal. Hippos are fast runners and weigh between one to two tons. They are herbivores that graze at night and secrete a reddish substance known as blood sweat for temperature control and infection prevention. Socially, male hippos are called bulls, females cows, and young ones calves. Hippos live around 45 years and can be aggressive. Their skulls are adapted for water, with vital organs positioned on top. Hippos have large incisors and can open their mouths wide. They live in groups called pods, rafts, or bloats, and mark territory with dung. Dominant males lead these groups, and hippos face threats from predators like lions and crocodiles.
