Deep water squid have joined a long list of species known to engage in bisexual behavior. It turns out that male squid are quite happy to ejaculate on other squid, regardless of whether they are male or female. Of course, scientists don’t really know whether the squid experience anything analogous to sexual desire or pleasure, or whether they can even distinguish between male and female partners in the dark of the ocean depths.
Other species known to engage in bisexual behavior include mammals with relatively large brains, such as bonobo apes and bottlenose dolphins, but also herd mammals and birds. And of course anyone who has a pet dog or cat has observed bicurious behavior in the natural world. Scientific manipulation of hormone levels in rats can also induce more homosexual behavior, though it’s not clear what this tells us, if anything, about behavior in humans.
