Ze Frank masterfully turns the bizarre, alien-like mechanics of nudibranch mating into a compelling lesson on evolutionary ingenuity. It is a brilliant example of how high-level science communication can be both rigorously informative and delightfully accessible.

think of it as a high five...Added:
The nutubbrank's genitals are located up near its head on the right side of its body because of course they are. This means that they have to position themselves so their right sides line up.
Think of it like a high five, but with no hands and four genitals. That's right, four. Nutubbranks are hermafhrodites, meaning that each is equipped with both a penis and a vagina.
I know what you're thinking. If I had that kind of luggage, I'd pack it myself. Sure, once in a while, a researcher will find a nutrank's penis inside of its own vagina. Don't judge.
It's a lot to keep track of. And quite frankly, if it's in the way, flopping around out there, it's the obvious place to put it. I mean, why aren't our pants pockets shaped like gloves? There's mysteries in this world. Doesn't mean you're trying to self-fertilize. Just some healthy curiosity. While mating, both nutubbranks put their penises inside the other's vagina, and both are fertilized in the process. Now, I'm not sure if you can see it, but if you squint, you might notice that the nutubbrank penis has a bit of a barbed hook sort of shape that can make uncoupling a bit of a So much so that the chromodorous reticula just lets it break off and grow back again. It's one way to do it. After mating, it is time for the nudrank to deposit its fertilized eggs. It does so in a series of beautiful strings and rosettes adorning the shapes of the ocean floor.
Thousands of little eggs that will become thousands of little babies. And the circle of life continues.
Listen, sometimes feeling safe in a shell isn't worth having your insides all twisted up or having an ass on your head. That might be too on the nose. I didn't mean like an ass on your nose.
That's I mean too literal. The point is sometimes you have to take a risk. Get out of that shell and untwist. Who knows what kind of crazy beautiful thing you might become.
Sorry, it felt like it should rhyme. And that is how the nutubbrank
