The Reaper's mandibles are definitely limbs, however, I don't think I'd go as far as to say that are evidence of a terrestrial heritage. It's likely that they used to be fins which then evolved into grasping/hunting appendages.

The Mesmer doesn't have any legs, those are fins.

The Lava Lizard and Hoverfish, on the other hand, absolutely display signs of having once walked upon land. It is possible that they both evolved out of water, perhaps on a Floating Island.
