Cool! The old movie that this looks like was called "Fiend Without A Face" (1958 - I have the original poster). It was shown on AMC channel a few weeks ago. The creatures had antennaes and eyestalks, but no eyes. Their spinal cords were a little more like tapering tails. They crawled around on the ground like big inchworms, waving their antennaes and eyestalks around.
