a drawing of an anthro "nemesignis banyulensis" species of nudibranch, also known as orange godiva nuidbranch walking through the city. She is older, glamourous and absolutely massive. She has a purse which appears stiff like plastic as she holds it in the air behind her. buildings are destroyed behind where she's walking.

PSA FOR ALL FLORDIANS!!! GET INSIDE NOW!!! Theres a category 3 [nemesignis banyulensis] heading STRAIGHT for Palm Springs!!!!

(reference in replies)

two slug cats sit on a rug drinking resting, they are rugged up in winter clothing. the one of the left looks like a demon with eyes covering their body and metal prongs for legs -their horns are clear and filled with fluid-. they are reading a book as opposed to the one on the right who is drinking a hot chocolate -this one is much brighter and has a tail very similar to a real nudibranch (sea slug).

hope yous are staying warm this winter :)))

Pencil drawing in a sketch book with some parts smudged. It shows a woman lying on her stomach with the upper part of a nudibranch draped over her like a blanket with odd bumps and rather spectacular feelers. She is smiling and has no hair.

I had some time to draw tonight. So why not show my progress for WIP wednesday.

I am still trying to figure out a nudibranch mermaid. I should attach the rhinophores to her head better, I think.

He/She glows.

A digital illustration of a blue galucus nudibranch with multiple eyes along its body, framed by a purple border with eyes all along it and two circular vignettes of a small crab and a brain coral, both with added eyes. The inner background is dark blue.

And last but not least, the late addition to the roster: the print version of the Blue Galucus Nudibranch pin. 💙✨️

the cover which says 2025 nudivember: 30 days of nudibranchs with half a nudibranch against a black watercolor background, the nudi is a gradient of purple to pink with yellow spots

a page from the book of nembrotha cristata featuring a watercolor illustration of a black sea slug with green spots, the text reads: Nudibranchs often match their food, either for camouflage or because their food actively colors them, and this green species feeds on a green compound tunicates on coral reefs in the Indo-West Pacific where they grow up to 50mm long.

Here's the cover and a sample page of my 2025 #Nudivember ebook zine.

Traditional drawing of a colourful seaslug called Mexichromis macropus. Its body is mostly white. The border of its mantle is decorated with orange stripes. It has purple bumps on its back. The rhinophores, gills, and tail end also have purple accents. The style aims for simple yet realistic.

A terribly late mexichromis macropus for #Nudivember day 24. I love these little sea creatures. They are so cute.

I want to turn this one into a nudibranch mermaid.

Watersoluble markers and waterproof liner. #traditionalart

Drawing of nudibranch which looks like a fluffy orange blob with a snowflake on top. The species is acanthodoris lutea. It has two orange feelers at the front. At the back, it has a circle of white gills which look like a snow flake. The background is blue.

Another late nudibranch for #Nudivember: Day 26 Acanthodoris lutea, also called the orange peel nudibranch.

Colored pencil on toned paper. #traditionalart

I'm wondering if this could possibly be the nudibranch Miamira moloch? Found in a rockpool near Mackay, Queensland, Australia after a week of cyclone weather, I'm guessing it may have been washed ashore?

OK, this has me truly stumped: possibly a #nudibranch (WAY out of my area of knowledge). It seems to resemble Miamira moloch, but any expert advice *very* gratefully received @nudibranch.bsky.social! Found in a tidal pool in Mackay, #Queensland. #seaslug #beach #wildlife #nature #sea #marine

Nudivember 2025: 30 Days of Nudibranchs by Saimi An art zine featuring watercolor illustrations of 30 different nudibranchs from around the world

I've finished the ebook version of my 2025 #Nudivember zine! I put it up on Itch since my webshop is currently closed.

This is my first time listing anything there so I hope I did it right. If I have time this week I'll add my other zines before I leave.

Thank you for participating all month! It was a joy to see your nudis every day.

#Nudivember concludes with Hallaxa fuscescens, a little black bunny.
Nudibranchs come in all shapes, sizes, and colors! Let them be a reminder that no creature design is too weird to exist.

#Nudivember Day 27

(Posca markers and acrylic gouache on blue pastel paper)

Thank you for participating!! I loved seeing your nudis all month long.

A drawing of a grey nudibranch with black spots, rhinophores, and gills.

And finally, nothing says #nudivember like December, and we should all marvel at Hallaxa fuscescens, and its perfect little creature energy.

It's done!!! 30 days of #Nudivember. 30 glorious nudibranchs. One tired artist.

It's the FINAL DAY of #Nudivember! And our last species to end the month is Hallaxa fuscescens.

Thank you to everyone who participated this year! I hope you had fun and enjoyed the nudibranchs and artwork.

#Nudivember day 29: Halgerda brycei, the forbidden pineberry
#nudibranch #seaslug #bumpy #art #SciArt

A nudibranch moving toward the camera over algae-covered rock. It is white, with a dark brown back and a black marginal band; it has black rhinopores and gills. The mantle is raised at the front so the oral tentacles are visible. #UnderwaterPhotography #MacroPhotography #Macro #Wildlife #WildlifePhotography #Nature #NaturePhotography

One last #Nudivember post. Here is Doriprismatica atromarginata coming to check you out. Most places seem to call this a black-margined nudibranch (rather boring) but I also saw it referred to as a cheesecake nudibranch, which is a much better name!

#MarineLife #Invertebrates 🌿

Aeolidiella sp. against black background. It’s curled up a bit and has two rows of groups of 4 brownish cerata.

I thought, I’d join in and post a nudibranch for the last day of #Nudivember. Here‘s Aeolidiella sp. I found in Spain in a rock pool

A drawing of a white nudibranch with black feathered rhinophores, red-tipped cerata, and black gills that look like a small leafless bush.

It's the penultimate #nudivember and today is Halgerda brycei, who has a built-in shrub.

I did phone this one in bc drawing nudibranches w this shape is very frustrating for me. And I think I like this result better anyway! Yay for learning to take art shortcuts
