Animals are multicellular eukaryotic organisms that form the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described--of which around 1 million are insects--but it has been estimated there are over 7 million in total. Animals range in size from 8.5 millionths of a metre to 33.6 metres (110 ft) long and have complex interactions with each other and their environments, forming intricate food webs. The study of animals is called zoology.
Animals may be listed or indexed by many criteria, including taxonomy, status as endangered species, their geographical location, and their portrayal and/or naming in human culture.

Phyla
The animal Kingdom contains some 35 extant phyla.
Basal animals are according to the following cladogram:
Animals: Porifera, Diploblasts
Diploblasts: Ctenophora, ParaHoxozoa
ParaHoxozoa: Placozoa, Cnidaria, Bilateria/Triploblast
Bilateria: Xenacoelomorpha, Nephrozoa
Nephrozoa: Protostomes, Deuterostomes
- Phylum Proarticulata + Disputed if this is in or out of Bilateria and Phylum Xenacoelomorpha is basal
