finlike

Resembling aquatic paddles

Resembling a fin in shape or function—a flat, thin projection used for stability or propulsion.

The submarine's finlike appendages helped it maneuver.

Often describes biological structures that aren't true fins but serve similar purposes: finlike growths on the creature's back.
