Nudibranchs are many divers favourite critters. There are a huge variety of these molluscs, and the vary immensely in shape, size and colour. The nudi ID books are called things like ‘1001 Nudibranchs’, which gives you some idea of their spread.
You can find them in cold water, temperate water and, of course, tropical water. A true nudibranch is a mollusc that has shed it’s shell after it’s larval stage. They are also commonly known as ‘Sea Slugs’. The name ‘nudibranch’ comes from the Latin nudus, naked and the Greek brankhia, gills or lungs. As the gills often are the feathery structure on their backs, and they lack a shell to cover them, you can see why they got there name.
Now this is a huge over-simplification of these creatures, but it gives you a brief idea of what they are.
This week I saw a nudi that I hadn’t seen before. As nudis can be as small as a couple of mm long, this is not perhaps that surprising. But this one was about 10cm (3.5”) long, bright yellow and moving around in the open..
It was, I found out later, a Marten’s Sidegill Slug, and this was a rather large specimen, Amba, the guide who found it, had never seen one either. Finds like this always make me wonder why I have never seen one before. It’s big, it’s stands out, it’s moving around and I do a lot of dives…. But this is why we go diving.. you never know what you are going to see and this is what I love about Lembeh, there are just so many critters out there, some you see regularly, some you just see once…you can go to the same dive site 100 times and see different critters every dive.
Enjoy the video of this rare and beautiful nudi.
Barb and I are of to the (hopefully) sunny UK later this week. It’s the Birmingham Dive Show and we have our KBR booth there. We’ll be there this weekend, on the 22nd and 23rd October. Please come and visit, we would love to see you. We’ll have our NEC Special, so it is a good time to book your KBR break.
