Today is national Sea Slug Day and one of my favorite sea slugs is the mighty Nudibranch. Nudibranchs are a group of soft-bodied marine gastropod molluscs which shed their shells after their larval stage.
There are over 3,000 different species of Nudibranch. They appear in every ocean and display many different shapes, sizes and colors.

Amazing wonder of nature.
It is! And I love it!
They are amazing – so beautiful……
Is there REALLY a national Sea Slug Day or did you just make that up??😅 😂 🤣
It’s totally made up. LOL! But not by me.
Facebook and Bing sent me alerts in the morning and I couldn’t resist. So, I did a few searches and it looks like it might be a thing to a small circle of people. 🙂

They are stunning creatures. Did you see the white ones in the Cook Islands, that locals snatch from the ocean, eat the insides while swimming in the water, which look like spaghetti, and then throw the hapless creature back in the sea? They regenerate.
No, I haven’t… I’ll have to look that up… that sounds pretty interesting. Never heard of humans eating them.
If only land based slugs were as varied and colorful as nudibranchs. Of course, some folks would still complain, “ew, slime.”
I’ve never touched one underwater but you can see the trail of slime as they move across coral, rock and or sand. I’ve never paid attention to them on land but I live in the city.
I had no idea that there were so many Nudibranch. Beautiful collection of pictures. You must have a great eye for spotting these tiny creatures.
It’s funny… When I’m on a dive and I’m not looking for them, I see them all over the place. The dives I decide to look for them… I can’t find any. LOL!
