Evolution, development, and random biological ejaculations from a godless liberal
They are utterly adorable, and I feel the stirrings of the maternal impulse deep in my mantle. The way their little bodies bob as they swim…awww, for cute.

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.
The authors of the paper, at least, get it exactly right.
In the Royal Society paper the team writes: “In the deep, dark habitat where O. deletron lives, potential mates are few and far between.
“We suggest that same-sex mating behaviour by O. deletron is part of a reproductive strategy that maximises success by inducing males to indiscriminately and swiftly inseminate every [squid] that they encounter.”
It’s every boy’s dream, just hosing everything down with semen, just to be sure.

Emily Baldry is six years old. Emily has a little plastic shovel. Emily dug up a 160 million year old cephalopod.
I’m 54, I have a little plastic spoon, and I’m eyeing the backyard. There used to be cephalopods swimming around in this neighborhood…of course, there were also some annoying glaciers that scoured the landscape. But I can dream!

This is tragic. A unique site where the giant cuttlefish migrates and breeds is under threat by the construction of a desalination plant that would render the local waters unsupportable to cuttlefish life. This must be stopped!
There is a petition: sign it.
