'Sex pest' seal attacks penguin
There would seem to be sexual predators in the animal kingdom too
An Antarctic fur seal has been observed trying to have sex with a king penguin.
The South African-based scientists who witnessed the incident say it is the most unusual case of mammal mating behaviour yet known.
The incident, which lasted for 45 minutes and was caught on camera, is reported in the Journal of Ethology.
The bizarre event took place on a beach on Marion Island, a sub-Antarctic island that is home to both fur seals and king penguins.
After 45 minutes the seal gave up, swam into the water and then completely ignored the bird it had just assaulted, the scientists report.
