Guess everything converges on crabs in evolution.

Maybe I'm forgetting some of my developmental biology lessons, but aren't these "legs" really "digits"?

I.e. they are the members of the fins without the membrane connecting them. So the relationship to other fish is like the opposite of bats' relation to other mammals.
