Australian zoologist, professor of Sidney university Rick Shine made a sensational discovery: many kinds of snakes are capable to become transvestites and to successfully pose as females by spreading female pheromones. Though this is not a caprice, but a way to get warm: after winter hibernation, snakes become sluggish, so their bodies’ temperature abruptly decreases. There is the only way to avoid becoming a prey: to pretend to be a female. The “female” will at once surrounded by a tangle of males who immediately warm their “girlfriend”. Luckily, snakes are peaceful animals: when the males get to know they have been swindled, they simply creep to look for real “ladies” secreting real pheromones. As for the rest, snakes are like human beings: Shine states almost every young snake passes through this stage it its development, though such “funs” are not in adult snakes’ way.
