Animals are multicellular, eukaryotic organisms of the kingdom Animalia (also called Metazoa). All animals are motile, meaning they can move spontaneously and independently, at some point in their lives. Their body plan eventually becomes fixed as they develop, although some undergo a process of metamorphosis later on in their lives. All animals are heterotrophs: they must ingest other organisms or their products for sustenance.
Animalia can be further divided into:
1. Porifera
2. Coelentrata
3. Platyhelminthes
4. Nematoda
5. Annelida
6. Arthropoda
7. Mollusca
8. Echinodermata
9. Chordata:
(a). Protochordata
(b). Vertebrata:
i. Pisces
ii. Amphibia
iii. Reptilia
iv. Aves
v. Mammalia
