Clown fish sex

Sex change is a process by which a person or animal changes sex — that is, by which female sexual characteristics are substituted for male ones or vice versa. Sex change may occur naturally, as in the case of the sequential hermaphroditism observed in some species. Most commonly, however, the term is used for sex reassignment therapy , including sex reassignment surgery , carried out on humans. It is also sometimes used for the medical procedures applied to intersex people. The term may also be applied to the broader process of changing gender role "living as a woman" instead of living as a man, or vice versa , including but not necessarily limited to medical procedures.

Sex change - Wikipedia

Subscriber Account active since. Father and mother clownfish are tending to their clutch of eggs at their sea anemone when the mother is eaten by a barracuda. Nemo hatches as an undifferentiated hermaphrodite as all clownfish are born while his father transforms into a female now that his female mate is dead. Since Nemo is the only other clownfish around, he becomes a male and mates with his father who is now a female. Should his father die, Nemo would change into a female and mate with another male.

What Happens to a Clownfish When It Changes Sex?

Nemo's father - a character from the popular animated movie 'Finding Nemo' - should have turned into a female, say scientists who found that male clownfish change sex if their mating partner dies. In the film Finding Nemo, a young clownfish's mother is eaten by a barracuda but his father, Marlin survives. Nemo, the only surviving baby, is then lost.

Sequential hermaphroditism is a unique reproductive strategy among teleosts that is displayed mainly in fish species living in the coral reef environment. The reproductive biology of hermaphrodites has long been intriguing; however, very little is known about the molecular pathways underlying their sex change. Our study has examined relative gene expression across multiple groups—rather than just two contrasting conditions— and has allowed us to explore the differential expression patterns throughout the whole process.
