wonder how toadfish evolved those front fins. Watching them waddle confidently on the sea floor is quite mesmerizing. Thought it was a weird looking piece of kelp at first, till it decided to stroll away from my voyeuristic gaze.
That was the point! A lot of fish have developed ways to use their fins to push against the ground or among kelp and whatnot, and is argued to be one of the mechanisms by which thicker and stronger bones would develop in the fins, and thus allow them to operate better as jointed limbs.
Heck, now I want to sculpt one of those critters. You should look into writing papers or novels. Your extensive knowledge and creative skills to create some awesome new tales. (Not that I believe in all that death of the author Rhubarb) It will be time consuming, but your fan base (er...friend base?) might really enjoy sumthing like that. gotta go happiness
