Dolphins 'resort to rape'

Dolphins appear to have a darker side, according to scientists who suggest they can resort to 'rape' to assert authority. Researchers found the marine mammals lead complex social lives, living in an "open society" where regular homosexual and bisexual relationships are found. The conclusions from the international team of scientists came after they spent the past six years studying the behaviour of 120 bluenose dolphins in Shark Bay, Western Australia. In one of the most extensive studies of its kind, male bottlenose dolphins were also found to organise gang-like alliances, in which they guard females against other groups.
