Using a front stop implies that this Section of the human body encounters stimuli, including foods, favouring cephalisation, the development of a head with perception organs along with a mouth. Many bilaterians have a combination of circular muscles that constrict the body, rendering it extended, and an opposing set of longitudinal muscles, that shorten your body;[135] these enable smooth-bodied animals which has a hydrostatic skeleton to move by peristalsis.
Protozoa. Later, the protozoans have been no longer viewed as animals and are designated with their unique biological kingdom. At present, the kingdom Animalia is comprised of the next extant phyla:

Vertebrates and invertebrates are two main divisions in the kingdom Animalia, differentiated mostly by the presence or absence of a spine.
