Hi @shaunm. Yep, absolutely. Aside from humans, many non-humans exhibit bisexual behaviour. Examples of mammals include the bonobo (formerly known as the pygmy chimpanzee), orca, and bottlenose dolphin. Examples of birds include some species of gulls and Humboldt Penguins. Other examples occur among fish and flatworms. In some cases animals will choose to mate with different sexes at different times in their life, and sometimes will perform mating acts with different sexes at random. Homosexual mating can also be seasonal in some animals like male walruses, who often engage in homosexual mating with each other outside of the breeding season and will revert to heterosexual mating during breeding season. Interesting stuff eh?!?
Well humans are animals and some humans are bi-sexual. The distinction between humans and other animals always amuses me. Humans have some special characteristics, but are they better or more important than the characteristics of other animals?
Nicely answered by Chris, and good point about humans by Steven. I also find it amusing when people refer to humans as not being animals. Does anyone remember on The Simpsons when Homer said that? 🙂
On a related note, there are some species (such as some molluscs) that are ‘hermaphroditic’, which means that they are both male and female at the same time. They have both male and female sex organs, and they mate by forming a group with several other members of their species, in a ring arrangement (this is called a ‘mating aggregation’). They all provide sperm to one other mollusc, and all have their eggs fertilised by one other mollusc – so they are all acting as both a male and female at the same time.
There are also some species that start off as either male or female, but then can change sex as they grow older.
