"Apart from homosexual behaviour, males, unlike females, in Shark Bay have also been recorded to perform synchronous displays," she explained.
Ms Nicholson's research team said they were "excited" to record the similarities between the dolphins in Mandurah and Shark Bay, hoping that the discovery of similar behaviour in a nearby but separate pod would help scientists better understand why homosexual behaviour in nature occurs.Petter Bøckman, an expert in homosexuality in animals from the University of Oslo, says that it's unsurprising that dolphins exhibit homosexual behaviour given their standing as a "intelligent social species." "Dolphins, being intensely social are also intensely sexual, both inside and outside of the mating season," he tells Attitude. "And since they need to socialise with same-sex flock mates too, a capacity for homosexual behaviour is an obvious advantage." He continues: "It's only the last 10 to 15 years we have started to understand how important sex is in the social life of many species, ranging from insects to birds and mammals. "The more complex the social interactions and the smarter the creatures involved, the more scope for "social sex", homo- and heterosexual. "The two top contenders for smart critters with complex social systems are dolphins and humans, so there's not really any surprises here."
