Here another one, seals raping penguins!
http://news.bbc.co.uk/2/hi/science/nature/7379554.stmThe bizarre event took place on a beach on Marion Island, a sub-Antarctic island that is home to both fur seals and king penguins.
At first glimpse, we thought the seal was killing the penguin
Why the seal attempted to have sex with the penguin is unclear
Sexual coercion among animals is extremely common: males of many species often harass, coerce or force females of their own kind to mate, while animals are also known occasionally to harass sexually a member of a closely related species.
Harassment is common among pinnipeds, the group of animals that includes seals, fur seals, and sea lions; and occasionally it happens between related species.
Male grey seals have been known to harass and mate with female harbour seals, for example, producing hybrids.
"Sexual harassment is often more commonplace in non-monogamous mating systems, and in species where males are physically much larger than the other sex and thus physically capable of coercion or harassment," says de Bruyn.
But this is thought to be the first recorded example of a mammal trying to have sex with a member of another class of vertebrate, such as a bird, fish, reptile, or amphibian.
'Too young'
Chinstrap penguins occasionally indulge in homosexual behaviour, and adelie penguins sometimes "prostitute" themselves to get stones for nest-building; while one in seven emperor penguins will change partners from one year to the next.
