Phylum – Aschelminthes, Class – Nematoda.

The body is divisible into head, trunk, and tail with a homocercal caudal fin.

The hindlimbs have four-clawed digits that help in perching and bear the weight of the body while standing.

Vibrissae are prominent and stiff hairs on the upper lip that are touch-sensitive (tactile).

Star fish (v)

Amoeba (i)

The body is divided into head, trunk, and tail.

Into head, thorax, and abdomen
