by Aaron Bloch
Dirona Albolineata!
Also known as the white-lined dirona, the alabaster nudibranch, or frosted sea slug!
I found out about these guys recently and they've been on my mind ever since, just figured I'd share! :3
chelidonura livida, you confusing yet mystic creature

Some creatures I've found, for my fellow creature enjoyers out there. Featuring "unidentified squirm" as we have been calling the pink worm (maybe echiurus echiurus), onchidoris bilamellata (rough-mantled doris/barnacle nudibranch), what I think is hediste diversicolor (ragworm), a hermit crab of some kind that jumped out of its shell when I picked it up, and cebidichthys violaceus (monkeyface prickleback) which I promise I didn't yoink out of the water they hide under the rocks during low tide.
sometimes i wonder why so many people think im autistic and then i remember im going as a nudibranch for halloween
