Isopods have many legs that look alike. Amphipods have legs of different shapes. Both eat bits of leaves, moss, dead worms and other small animals that drift in the cave streams. Both of these animals belong to the crustacean family. They are usually brownish in color and have eyes.
Flatworms crawl over damp areas in search for their food.
They leave a sticky trail which causes isopods and amphipods to become stuck. Then the flatworm is in for a feast. Cave crickets are pale brown and have smaller eyes than those crickets that are surface dwellers. Cave crickets love the warm, moist cave. However, they may leave at night in search of food.
