flipperlike
Resembling a fin
Resembling a flipper—the broad, flat limb of marine animals like seals, sea turtles, or penguins, adapted for swimming.
The term describes anything with that wide, paddle-shaped quality: flipperlike hands, flipperlike appendages.
Sometimes used for the rubber swim fins worn by divers.
