An unusual strategy for attracting females, that of homosexuality. Poecilia mexicana, a freshwater tropical fish belonging to the Poeciliidae family, of the order Cyprinodontiformes, uses an infallible technique to conquer the specimens of the other sex, giving rise to homosexual relationships. She revealed one study published by some German biologists on Royal Society journal Biology Letters.
The females of mexican poetry they are really very difficult: they are attracted only to large dominant and colorful males. Sad fate for smaller, dull colored males, who had to find new strategies for attract females. And they found the flaw of the opposite sex: they love womanizers, so it is impossible to make them "jealous" with other females, while it works with males. “We were very surprised to find that the homosexual relationships they had the same influence on female preferences as heterosexual relationships, ”says David Bierbach of the University of Frankfurt.
The less showy males of this species, in fact, can persuade a female to mate "Flirting" with other males. Basically, they nibble on each other around the genitals, a sign that they are ready for mating. Seeing this, females identify them as potential sexual partners. Probably because this behavior can improve the male's ability to pass on his genes, attracting females who wouldn't be interested in him otherwise. "This implies that sexual activity as such is an index used by females to assess the quality of males, and this may also be true for other species," Bierbach thinks. Homosexuality, in fact, is very widespread among animals and has been observed in about 450 species.
