Word Origin and Notes
The word pinnatiped comes from the Latin pinnatus, meaning "feathered" or "finned" (referring to the flipper shape), and pes, pedis, meaning "foot." It literally means "fin-footed" or "feather-footed," describing the flipper-like limbs. Its use has largely been superseded by pinniped.
