some shady female penguins cheat on their partners in what scientists believe is the only other animal in nature to prostitute itself - the female will shag a male in return for some suitable nesting rocks and the like, some times the male brings some more stuff over after the shag as a sort of tip... not answering the question i know but interesting none the less
