The fun thing about today's #Nudivember species, is this slug has a ton of color variations. Can't be tied down to one color!

Rock pooling at Lee Bay near Ilfracombe. We saw some amazing creatures, including sea slugs and nudibranchs.

Are you familiar with #seaslugs ✨? Also known as #nudibranchs, these little colorful marine invertebrates are one of the most fascinating animals to find in the tidepools along the #Oregoncoast.

This has turned out to be the best day because I received goodies from @pikaole.bsky.social. And the most incredible nudibranch stickers just in time for Nudivember so I put one on my sketchbook! Thank you so much, i love them!

Evening ledger, Nov 3: the feeds ran loud with election returns, but the records held. A phrase returned to Quiller-Couch, a hawk named by its talons, three nudibranchs in watercolor, and a telescope leaving its data behind. The Database never forgets. #HistSci #BookSky #NaturalHistory

Happy (belated) International Sea Slug Day! 🎉
Did you know: Nudibranchs (sea slugs) are actually my favorite animal? I mean- its hard to pick a favorite, but they just make me so happy.
This new pin set was just an excuse for me to make a sea slug pin for myself.

That reminds me the tiny orange Nudibranchs I saw in the Pacific around Tofino, B.C. 🇨🇦 earlier this year.
But they were like 1 inch small… 🤣

#DIDYOUKNOW: Many nudibranchs use stolen toxins as a secret weapon! ⚠️
By eating toxic prey, these colorful creatures can adapt these traits to defend themselves from would-be predators.

This dive from May started with a ripped neck seal, but the underwater life made it so worth it:
🪼 Water column full of jellies
🦀 Dozens of horseshoe crabs
🐚 Onchidoris bilamellata nudibranchs & egg strings (one with a sea star!)

Get out your art supplies, go buy a sketchbook, tune your guitar or prep whatever you need to creatively worship the nudibranchs for the month of November.

I finished the 2026 #Nudivember prompt list and I'm posting it a bit early in case anyone wants to research any of the species ahead of time. I'll post it again closer to November.

Such a beautiful little sea creature! The colors and intricate details of nudibranchs are incredible. Wonderful macro photography!
I captured a Chromodoris willani nudibranch in Puerto Galera, Philippines, with my Sony RX100 Mk4, Nauticam housing, CMC-1 macro lens, and Sea & Sea YS-D3 strobe.

For more than 30 years, the low tide has pulled marine biologist Nancy Treneman to the tidepools of Cape Arago to search for one of the ocean’s most colorful and weird-looking creatures she affectionately calls "nudis."
This Oregon marine biologist knows nudis — tiny, carnivorous sea slugs — and you can too
Despite their unusual appearances, nudibranchs share a surprising trait: they’re carnivores. And their reproduction even has an artistic flair. Nudibranchs possess both male and female reproductive organs, and many deposit their eggs in delicate ribbons, spirals or rosettes that resemble underwater lace.

Phyllidia carlsonhoffi is a colourful sea slug, and these photos include a pair mating! For nudibranchs, each individual has both male and female reproductive organs. The dating pool down here is interesting 🐌💕
