Clam with the tongue

[Nibles]

There is a sea creature (a clam or fish or something) that has a tongue like appendage that it uses for bait, and when the fish approach it it gets eaten.

Alligator snapping turtles do that. I believe there is also a type of rockfish, but I can't recall the name. These actually use their tongue as bait.

There are others (now that I re-read your post) that have "tongue-like appendages" which they use much like a deep-water angler fish. Frogfish in the tropics are relatives of the angler, but have a pink, wriggly bit like a worm in place of the angler's bioluminescent globe.
