Testing out the possibility of using my new fude foundation pens for #Nudivember with a quick watercolor. I think I like it.

And the Platinum carbon ink stayed put under the watercolor, it's the first time I've used it.

Some potential great news from today - looks like I may have finally found a way to get some real scientists to start describing some of the many undescribed #Nudibranch we have here in the UAE. This spectacular creature will hopefully be the first on the list.

#Invertober2025 Day 22: Clione limacina. PASTELS FOR GOODNESS SAKE.

Verdict: if Eve from WALL-E were a marine invert this is the one she would be. Also haven’t used pastels since I was at school FOR VERY GOOD REASON.

Happy #Invertober day 22!

Sea angel (Clione limacina)

Repost today of one of my earliest attempts at a more painterly style. I could probably redraw this with a more photorealistic effect today, but I don't think it would be any more charming than this!

Digital painting of a slug-like sea creature with appendages that look like wings and horns. Its body is semi-transparent so that you can see its internal organs glowing orange and gold.

Happy Docktober! Have one of my favorite nudibranch dock finds. Doto sp (potentially Doto amyra)

Two teeny tiny nudibranchs snuggled up on some algae. They have simple rhinophores with a single rod coming out of a wider cylinder. Their backs are covered in cream colored cerata that have a very fluffy looking internal texture and lots of white polka dots.

Peachtober Day 3 - (Sea) Slug 🪸 ウミウシ

I looove nudibranchs, they are all so beautiful! (Fun fact: sea slugs are called "sea cows" in Japanese. Maybe because of their horns!)

ウミウシは全種類きれいで大好きです！（今日のピーチトーバー課題は英語で「ナメクジ」ですが、ウミウシは英語で「海のナメクジ」とも呼ばれます。）
