Nature pushing borders Genital morphology is one of the most diverse and rapidly evolving features of animals with sexual reproduction.In species with traditional sex roles, strong selection due to intense sexual competition has generally shaped more complex genitalia in males than in females.In some cases, the evolution of this so-called role reversal comes with stunning adaptations.There are a variety of examples in nature in which males are the caregivers or females compete for access to mates.Instead, the way each sex behaves depends on several factors such as asymmetries in parental investment, sex-ratio or the availability of mates.So the next time you see an animal with what seems to be an intromittent sexual organ, don't take for granted it's a male. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission.This implies males can produce a much larger number of gametes – the cells that merge during sex – than females do, which, in turn, entails important consequences for differences between the sexes.

Among vertebrates, the females of the spotted hyena (Crocuta crocuta) have developed a pseudo-penis structure.Although their genitals are female in function, they are male in form.But another remarkable example, which constitutes a huge step towards understanding the selective pressures acting on the sexes, has been recently observed in cave insects of the genus Neotrogla.Examples include the jacana water birds, New Zealand's kiwi birds, the tinamou birds native to Central and South America and some shorebird species.Then, there are sea horses, among whom males get pregnant and carry the offspring during development; amphibians such as some species of frogs of the genus Dendrobates and; mammals such as the African topi antelope (Damaliscus lunatus).

Neotrogla inhabit caves where water and food resources are very scarce.
