Monster Girls - Tritonia

I'd like to add that from a concept and design perspective, the Tritonia is easily one of my favorites.
Marine invertebrates are actually my field of study, and a couple of touches here just make me happy.

The hair over where her human eyes, if she has any, the rough translation isn't exactly clear, would be, hairstyle, and the eyestalks makes her really look like several species of nudibranch.

The entry mentions them not being able to feel through the tentacles on their back. This brings to mind how many nudibranch appropriate the stinging tentacles on their back from consuming anemones.

It talks a bit about their swimming, and the way it describes makes me think of the Spanish Dancer sea slug. However, they're far more similar the Blue Glaucus in terms of appearance, being frilly and blue.

Tritonia itself is a genus of nudibranch.

Goes without saying, they're mentioned to be really soft cuddly. Nudibranch actually do possess an internal shell similar to the cuttlebone in cephalopods. However, it's composed of proteins, as opposed to calcareous aragonite. e/i; they're soft-bodied all the way through.

So, is it a herm too?
