The recent discovery of Vulvaris majorieii was quite a shock to the marine biology community, as it appears this highly toxic species has been hiding in plain sight all along.
Unlike all other nudibranches Vulvaris majorieii is not hermaphroditic, but unlike other nudibranches the male nudibranch tears it’s withered genitalia off after insemination, and presents them as a food gift to the female. It may be that this is an act of self-defence, as the female of species Vulvaris majorieii is known to eat it’s offspring, so possibly this act of simpering capitulation is a life saver for the male. However, the male nudibranch has also been observed slavishly feeding their offspring to the female, so possibly it’s just a cannibalistic species.
Vulvaris majorieii is a mistress of disguise, falsely presenting itself as palatable to other species and other nudibranches, whilst all the while secreting an extremely noxious toxin. The toxin calms it’s victims into a sensation of safety, so much so that the female Vulvaris majorieii can often be seen surrounded by a larder of willing victims who have been lulled and gulled into her proximity.
The toxin secreted by Vulvaris majorieii is dangerously venomous to humans. Do not be tempted to lick this nudibranch, no matter how appetising it may look! Short term exposure to it is likely to result in feelings of superiority, grandiosity, and even delusion, but long term exposure will just leave you weak and incapacitated, a victim of hubris.
If you need to lick something poisonous, you’d be better off slurping on a cane toad than this malignant marine mollusc.
