Bisexual fish boost mating chances: Study

 
 

PARIS (AFP) - In an unusual mating strategy, hard-up males of a tiny, promiscuous fish species engage in homosexual acts in a bid to entice females to copulate with them, a study said on Wednesday.

And it works.

Researchers said small, non-dominant Atlantic molly males, often overlooked for larger, flashier rivals as mating partners, rose vastly in the esteem of females that observed them copulating - regardless of the partner's sex.

Some female animals are known to show a preference for mating with males they had observed coupling with other females in a phenomenon known as "mate choice copying".
