A widely distributed old-fashioned type of animal, somewhat like a
permanent caterpillar. It has affinities both with worms and with
insects. It has a velvety skin, minute diamond-like eyes, and short
stump-like legs. A defenceless, weaponless animal, it comes out at
night, and is said to capture small insects by squirting jets of slime
from its mouth.]
