ocellaris clownfish
The ocellaris clownfish (''Amphiprion ocellaris''), also known as the false percula clownfish or common clownfish, is a marine fish belonging to the family Pomacentridae which includes clownfishes and damselfishes. ''Amphiprion ocellaris ''are found in different colors, depending on where they are located. For example, black ''Amphiprion ocellaris ''with white bands can be found near northern Australia, Southeast Asia, and Japan.〔 Orange or red-brown ''Amphiprion ocellaris ''also exist with three white bands (like mentioned above) spanning from its body and head. ''Amphiprion ocellaris ''can be distinguished from other ''Amphriphon ''fish based on the number of pectoral rays and dorsal spines. ''Amphiprion ocellaris ''are known to grow about 110 mm long. Like many other fish species, females are, however, larger than males.〔 The life cycle of ''Amphiprion ocellaris ''varies in whether they reside at the surface or bottom of the ocean. When they initially hatch, they reside near the surface. However, when ''Amphiprion ocellaris'' enters into the juvenile stage of life, they travel down to the bottom to find shelter from a host anemone.〔 Once they find their anemone, they form a symbiotic relationship with them.〔〔
==Phylogeny==
The species ''Amphiprion ocellaris'' belongs to the class Actinopterygii which contains bony fish and ray-finned fish. ''A. ocellaris'' is the most basal species in the genus ''Amphiprion'' which is closely related to the genus ''Premnas''. The species' most closely related ancestor is ''Amphiprion percula'', the Orange clownfish. It is thought that ''A. ocellaris'' specialized after diverging from the ''Premnas'' genus, and scientific evidence confirms that all clownfish belonging to the genus ''Amphiprion'' could withstand the stings of only one type of anemone, after further diverging the 28 different species of clownfish including ''A. ocellaris'' specialized to be able to resist the poisonous stings of many different species.
