Indiscriminate squid sperm distribution is not "bisexual"

PZ Myers explains why the discovery that the male of a species of squid reproduces by showering other squids with sperm regardless of their sex doesn't make the squid "bisexual." Not that there's anything wrong with that.
This is a beautiful illustration of the flaw in applying human sexual conventions to non-human organisms. researchers studying deep-sea squid found that all of the squid, male and female alike, were speckled with sperm packets — the males just flick these things out at any passing squid, on the chance that it's a female. It's silly to call this bisexuality or same-sex mating, though — it's pretty darned common in invertebrates. Many species of sea urchins, for instance, indulge in synchronized ejaculatory orgies: on one or a few days a year, all of the individuals in a colony simultaneously spew eggs and sperm into the water, to the degree that they can turn the ocean milky white with semen and ova. Do we call that homosexuality? Is it even right to refer to it as an "orgy"? It's just indiscriminate fertilization.
No, no, no — this is not bisexuality or homosexuality
