Tasting hairs on the legs of a roach can not only help it determine a food source, but help it avoid pesticides as well. Glycocides -- poison baits mixed with glucose -- were traditionally used to dose the sweet-loving cockroach with lethal toxins.
Caecilians, which are legless amphibians, use muscle contraction to move from place to place. Certain species of caecilians move from side to side, much like snakes. Adult amphibians, belonging to the orders Anura and Caudata, use methods of locomotion such as walking, hopping, and jumping.
