A large baleen whale, particularly a fin whale, named for its prominent dorsal fin and streamlined body.
From fin plus the agent suffix '-er' (one who has fins or one that is fin-like). Originated in whaling terminology in the 1800s when whalers needed specific names for whale species they hunted.
Fin whales are the *second-longest* animals ever—only blue whales are bigger—but they're so sleek and fast they can swim at 25 mph, making them the cheetahs of the ocean!
