Which animals living as prostitutes?

Adelie penguins build nests in gravel to lay their eggs. When nearby pairs are distracted, these penguins do not hesitate to steal their stones. And some females are engaged in prostitution to earn some stones, even though they already have a long term partner.

Why sometimes tigers are born with white fur?

There is an opinion that in the nature there are some albino tigers, however thats a false opinion. White fur with black stripes and blue eyes occurs only in Bengal tigers due to mutation of their genes, the probability of mutation is 1 to 10,000. White tigers are reproducing very well in unnatural habitats, nowadays in the zoos around the world there are around 100 white tigers, and all of them are descendants of 1 tiger that was found by hunters in 1951.

Which animals are "badly" adapted for repruduction?

Big pandas are counted to be extinct animals and they have one of the world's smallest birth rates. Chinese scientists at Chengdu Panda Centre came to conclusion that low birth is due to the fact that pandas were "badly designed" by nature. The females of Big pandas can sexual act only once a year for the length of 72 hours. While males have extremely small penises and due to that fertilization of a  female egg only possible in one sexual position, which Panda males don't know.
