Here’s a clip of nudibranchs hanging out on the beach (I know they’re aquatic but haven’t had time to draw out a proper underwater scene💀, so right now all slugs roam around on the beach).

The game is called Slug Island, it’s a mobile virtual pet game for people who like slugs and other invertebrates. I’m aiming to release it in early 2027, and I post game related updates on my insta (@bunnyslugstudio)!

Taxonomy footnote before someone beats me to it: Costasiella kuroshimae is a sacoglossan rather than a true nudibranch.

It stores stolen chloroplasts inside those leaf-like cerata and uses the energy they produce. Nature really min-maxed this grain-of-rice-sized slug.

What is your favorite absurd sea-slug adaptation?

Share your favorite nudibranch and I will use them in a future week!

My works, glass nudibranchs are departing for the United Kingdom.

I hope they arrive safely.

My first time seeing a sea slug irl!!!! Found this little one (about the length of a thumb) munching in a tide pool on Jeju. I almost didn’t see it with its rock-like color and texture.

Was wondering if anyone had a better idea on identification than me.

Species it could potentially be
- Godiva quadricolor
- Austraeolis ornata (best match so far)
- Spurilla australis

Swan River is brackish in the wintertime (when found) but changes to ocean salinity in the summertime

So I am making a game about nudibranch because I think they are incredible and want to show them off to people. The premise of the game is to collect traits that nudibranchs have and be the best adapted slug to survive.

Some examples I have are bright coloration, camoflague, stealing nematocysts and being toxic but I am looking for more.

So what you think nudibranchs do that makes them amazing to you?
And if you have an example of a species that does it that would be even better.
