So what’s the good news?
But they are present, and damned effective. Earthworms use them to “grip” the soil and assist with locomotion – an important trait for a cylindrical, slimy invertebrate. They also help the earthworm resist attempts to remove it from the ground - anyone who has ever tried to pull up earthworm probably learned that even if you have the grip of a professional free-climber, the best you will end up with is half an earthworm. Scale this trait up to a whale-sized worm, and very well-anchored organism would result. In fact, in a scene early in the movie, one of a graboid’s “tongues” manages to clamp onto the axle of a pickup. The pickup is able to get away after flooring the gas, but it only succeeds in pulling the “tongue” out by its base, leaving the rest of the graboid likely in exactly the same position it started, albeit in much pain.

perhaps that's not such a great loss after all...
