The term 'WALRUS' Cousin' can refer to three different animals: the SEAL, the sea lion, and the earless SEAL. The SEAL is a four-letter word, the sea lion is a seven-letter word, and the earless SEAL is an eleven-letter word. Seals are semi-aquatic mammals that live in the Arctic and Antarctic regions, and they are closely related to walruses. Sea lions are also semi-aquatic mammals, but they are more closely related to bears than walruses. Earless seals, also known as true seals, are found in the northern hemisphere and have no external ears. All three of these animals are closely related to the WALRUS and can be considered its cousins.
