Marine biologist Williams Haddad and his team discovered that male fur seals sexually assaulted and raped king penguins on Marion Island, about thousand miles south of Cape Town in the Indian Ocean.
Haddad had already published a paper about the finding in 2008 and says he noticed similar behavior in 2009, 2011 and 2012. A video of one of the encounters was captured and uploaded on YouTube.
"This is very weird because it´s hair and feathers, mammals and birds. It´s such a big gap, it´s unheard of," Haddad said. It is possible that penetration might also have occurred. In one encounter, the seal even killed and devoured its victim.
