Cockroach is a swift runner as well as a flier. The six legs are helpful in walking or running, when the cockroach is at rest, the coxae of the legs lie back against the body and the first legs are directed forward, the hind legs are stretched out posteriorly and the middle legs take whatever position is convenient.

Locomotion in snail

The snail propels itself by deforming a layer of mucus beneath it via muscular contractions in its foot muscle. This unique form of locomotion allows snails to traverse almost any obstacle, including the ability to climb steep inclines.
