Though they’re technically sea lions (not seals — you can tell by their visible ears), Juan Fernández Fur Seals are often called “lobos” in Spanish, meaning “wolves.” But calling them “seawolves” in English can be misleading — they’re not aggressive predators, just incredibly charismatic marine animals.
