According to BBC News, a seal has been caught attempting to rape a penguin.
"Why the seal attempted to have sex with the penguin is unclear. But the scientists who photographed the event speculate that it was the behaviour of a frustrated, sexually inexperienced young male seal....
"...Equally, the incident may have arisen because the seal was 'play-mating'.
"'It was most certainly a once-off and has never previously or since been recorded anywhere in the world to our knowledge,' says de Bruyn.
"The penguin did not appear to have been injured by the seal, the scientists report. "
