The main deuterostome phyla are the Echinodermata and the Chordata. The Ecdysozoa are protostomes, named after their shared trait of ecdysis , growth by moulting. All of these have a body divided into repeating segments , typically with paired appendages. Two smaller phyla, the Onychophora and Tardigrada , are close relatives of the arthropods and share these traits.

The ecdysozoans also include the Nematoda or roundworms, perhaps the second largest animal phylum. Roundworms are typically microscopic, and occur in nearly every environment where there is water; [] some are important parasites. These groups have a reduced coelom, called a pseudocoelom.

The Spiralia are a large group of protostomes that develop by spiral cleavage in the early embryo. All of these are grouped as the Platytrochozoa , which has a sister group, the Gnathifera , which includes the rotifers. The Lophotrochozoa includes the molluscs , annelids , brachiopods , nemerteans , bryozoa and entoprocts. These two groups have long been considered close relatives because they share trochophore larvae.

In the classical era , Aristotle divided animals , [d] based on his own observations, into those with blood roughly, the vertebrates and those without. The animals were then arranged on a scale from man with blood, 2 legs, rational soul down through the live-bearing tetrapods with blood, 4 legs, sensitive soul and other groups such as crustaceans no blood, many legs, sensitive soul down to spontaneously-generating creatures like sponges no blood, no legs, vegetable soul.

Aristotle was uncertain whether sponges were animals, which in his system ought to have sensation, appetite, and locomotion, or plants, which did not: In , Carl Linnaeus created the first hierarchical classification in his Systema Naturae. Since then the last four have all been subsumed into a single phylum, the Chordata , while his Insecta which included the crustaceans and arachnids and Vermes have been renamed or broken up. By , in his Philosophie Zoologique , Lamarck had created 9 phyla apart from vertebrates where he still had 4 phyla: In , Ernst Haeckel divided the animal kingdom into two subkingdoms: Metazoa multicellular animals, with five phyla: The human population exploits a large number of other animal species for food, both of domesticated livestock species in animal husbandry and, mainly at sea, by hunting wild species.

A smaller number of species are farmed commercially. Animals have been hunted and farmed for their fur to make items such as coats and hats. Working animals including cattle and horses have been used for work and transport from the first days of agriculture. Animals such as the fruit fly Drosophila melanogaster serve a major role in science as experimental models.

People have used hunting dogs to help chase down and retrieve animals, [] and birds of prey to catch birds and mammals, [] while tethered cormorants have been used to catch fish. However, the most kept pet species are mammals, namely dogs , cats , and rabbits.

Animals have been the subjects of art from the earliest times, both historical, as in Ancient Egypt , and prehistoric, as in the cave paintings at Lascaux. In both Japan and Europe, a butterfly was seen as the personification of a person's soul, [] [] [] while the scarab beetle was sacred in ancient Egypt. The signs of the Western and Chinese zodiacs are based on animals. From Wikipedia, the free encyclopedia. For other uses, see Animal disambiguation.
