Men should be interested in this; certain species of cichlids have developed a gene that makes females suck sperm into their mouths. Yep, something that human men would love.Anyway, for most fish, reproduction occurs when the sight of a brightly colored male triggers females with fertile eggs to start releasing them. In cichlids, females incubate the eggs in their mouths. Normally, sperm released into the water by a male nearby will fertilize the eggs.
Ah, but in some species of East African cichlids, females are "encouraged" by oval yellow markings found on the anal or pelvic fins of the male. These resemble eggs and when a female approaches the male, she tries to vacuum it up in her mouth --- and gets a mouthful of sperm in the process.
Walter Salzburger at the University of Lausanne, Switzerland led the study, and his team identified the gene, csf1ra as the "culprit." DNA samples from 19 cichlid species, nine with egg spots on their fins and 10 that did not, showed that the species that had evolved most recently had a mutation in the csf1ra linked to the egg spots.
Salzburger says this shows that the dummy egg spots are a genetic trait that provides a selective advantage because they encourage females to participate in oral copulation.

just disgusting, thank God I am not that type of female fish
I am so sick after reading the article. I really find it disgusting! I have to do that to my husband and is really gross but women have to do that to our husbands so they wont go looking for prostitutes, but doing that to a fish is outrageous and sickening I rather be Heidi Klum and her horrible gorilla husband!

Where can I buy theis wondergul female fish? I will marry her in a second and dump my cowlike wife, good for nothing .Pvayeos the king or Prusia!
I will do the same I mean to Damian Lewis, just like Merie Duplessis from Idaho. Comodore Sampatortas from San Luis Missouri

Every morning as soon as I wake up I go to the fresh air and with my arms high and above my head I thank God that He did not make me a woman. All the things they have to do in order to deserve a place under the sun and besides that these pathetic creatures have such an array of short and stupid ideas. Just read the non-sense that they write and I bet they must be thinking that they are literary geniuses.
Sounds Fantastic.
Women should not be disgusted
by the very normal, sane,
desire of men to have their
penis sucked.
It is hot, it is pleasureable
and should be something she
should be delighted in doing.
