blue headed wrasse asexual


Read the original article.

Typical behavior of a Blue Headed Wrasse (Thalassoma bifasciatum). Large females and some males can permanently change coloration and/or sex and enter the terminal phase coloration, which has a blue head, black and white bars behind the head, and a green body.

Minimum Tank Length/Size: The density of the type of male depends on the size of the reef. This occurred although large males originally continued to defend and display at the original sites. This wrasse doesn't bother corals but it will eat crustaceans and invertebrates.

Females visit these groups to spawn and release eggs in a 'spawning rush'. Perhaps an understanding of epigenetic changes in fish sex can offer us valuable insight, as we wrestle with new ideas about human sex and gender. Like many other wrasse species, the bluehead wrasse is a protogynous sequential hermaphrodite; individuals may begin life either as males or females, but females can change sex later in life and become males. Mini reef aquarium guide. (2005). If this male is removed from the group, something extraordinary happens: the largest female in the group changes sex to become male. These offsprings are produced by mitosis. That said, humans share with all vertebrates (including fish) about 30 genes that control ovary or testis differentiation. Best regard, Liu Wei Chung. Only the male has a blue head – signalling his social dominance over a harem of yellow-striped females. Not so with the blue-headed wrasse, a tropical fish that darts about amongst the corals and sponges in shallow Caribbean waters. Injections of AVT can induce sexual and aggressive behaviors in terminal phase male bluehead wrasses while injections of fluoxetine (tradename: Prozac) can reduce aggressive behaviors by terminal phase males. It is very active during the day, enjoying a lot of rockwork with nooks and crannies for retreating as well as for sleeping at night. Though they will not bother your corals they will eat your small crustaceans and invertebrates. [5], Though bluehead wrasses are common cleaner fish in the coral reefs they inhabit, they avoid cleaning piscivores such as the spotted moray, the graysby, and the red hind. This suggests that transitioning from ovaries to testes in wrasse involves reversing the cell differentiation process – something scientists have argued about for decades. Interestingly, behavioral sex change occurs even in females whose gonads (ovaries) have been surgically removed prior to becoming socially dominant. A specific social system exists within the male bluehead wrasses - terminal phase males (which are the most aggressive and have the "highest" ranking among the males) and initial phase males (which mate when they can get a chance in a larger group). This included genes known to “epigenetically” regulate the activity of other genes. A study was done to estimate the relative roles of each sex in choosing the location of such sites.

[2], Young/small females and males have yellow upper bodies and white lower bodies, often with green or black lateral stripes and occasionally dark vertical bars.
