A post at Atomic Nerds sent me into Wiki-land, looking at tetrapods, where I found one sort that are anything but four-footed. They do have a well-developed skeleton and strong, strong skulls, but if you met one, you'd probably take it for Conan the Earthworm: caecilians. They're actually more like Mr. Magoo, as most sorts have eyes so simple all they can see is if it's dark or light out; this hardly matters, as they spend most of their workday tunneling through wet dirt like organic piledrivers.
They're the guys parent earthworms would (if they had, you know, speech-capable brains) tell their young to eat all the dirt on their plates so's they can grow up to be like; ain't gonna happen but hey, gotta have goals. (Then again, there's evidence they bear the same relation to worms that sparrowhawks do to sparrows...).
Have to wonder if the writer of Tremors had met up with one of these.
