The film is set in Africa, so all the "seals" are Cape Fur Seals (Arctocephalus pusillus). They are much more closely related to sea lions than true seals, and share with them external ears (pinnae), relatively long and muscular foreflippers, and the ability to walk on all fours. In the US, they'd be easily confused with California sea lions (Zalophus californianus), because both fur seals and sea lions are from the same family, commonly known as Eared Seals (Otariidae).
