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 ...
Ocellaris clownfish, Amphiprion ocellaris, a protandrous animal species In general, protandrous hermaphrodites are animals that develop as males, but can later reproduce as females. [ 11 ] However, protandry features a spectrum of different forms, which are characterized by the overlap between male and female reproductive function throughout an ...
Marine fish can produce high numbers of eggs which are often released into the open water column. The eggs have an average diameter of 1 millimetre (0.039 in). The eggs are generally surrounded by the extraembryonic membranes but do not develop a shell, hard or soft, around these membranes. Some fish have thick, leathery coats, especially if ...
A sex-determination system is a biological system that determines the development of sexual characteristics in an organism. [1] Most organisms that create their offspring using sexual reproduction have two common sexes and a few less common intersex variations. In some species, there are hermaphrodites. [2]
