Clownfish or anemonefish are fishes from the subfamily Amphiprioninae in the family Pomacentridae. Thirty species of clownfish are recognized: one in the genus Premnas, while the remaining are in the genus Amphiprion. In the wild, they all form symbiotic mutualisms with sea anemones. Depending on the species, anemonefish are overall yellow ...
The physiology of underwater diving is the physiological adaptations to diving of air-breathing vertebrates that have returned to the ocean from terrestrial lineages. They are a diverse group that include sea snakes, sea turtles, the marine iguana, saltwater crocodiles, penguins, pinnipeds, cetaceans, sea otters, manatees and dugongs.
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.
In fact, protandrous hermaphroditism occurs in many fish, [15] mollusks, [12] and crustaceans, [16] but is completely absent in terrestrial vertebrates. [11] Protandrous fishes include teleost species in the families Pomacentridae, Sparidae, and Gobiidae. [17] A common example of a protandrous species are clownfish, which

[2] Like other species of the genus, the fish feeds on algae and zooplankton in the wild. [3]
Cymothoa exigua is not believed to be harmful to humans, except it may pinch if separated from its host and handled. [ 14 ] In Puerto Rico, C. exigua was the leading subject of a lawsuit against a large supermarket chain; it is found in snappers from the Eastern Pacific, which are shipped worldwide for commercial consumption.
This is known as the ocellaris clownfish and sometimes referred to as the "false percula clownfish" or "common clownfish" due to its similar color and pattern. The "easiest" way to distinguish the two species is the fact that A. percula has 10 spines in the first dorsal fin (rarely having 9) and A. ocellaris has 11 (rarely 10), which is a more ...
Fish vision shows adaptation to their visual environment, for example deep sea fishes have eyes suited to the dark environment. Fish and other aquatic animals live in a different light environment than terrestrial species. Water absorbs light so that with increasing depth the amount of light available decreases quickly.
