So apparently it’s #MolluscMonday so here is one of our local star #Nudibranch in the UAE. Hypselodoris dollfusi is relatively common but no less spectacular.

So first dive in over a year - and first dive in the UAE in about 4 years. A few Nudibranch were around which makes it nice. Here is the first one - an undescribed Phyllodesmium down at 21m.

So this is one that shows up a few times here in the UAE - was historically referred to as Hypselodoris capensis - but is now more likely to be undescribed. This was found on a wreck down at 21m.

This is Costasiella kuroshimae, the sea sheep.

It's not a nudibranch, it's a sacoglossan, another mollusc clade. The green color is a tip-off: sacoglossans are herbivorous where nudis are carnivores.

Like nudibranchs they can eat things and then repurpose cells from them, in this case chloroplasts

And to finish if off, here's some miscellaneous critters I only got one or two shots of, from left to right: a three lined aeolid nudibranch (Coryphella trilineata), a baby rock scallop (Crassadoma gigantea), a brittle star (Ophiothrix spiculata), and a Heath's dorid (?) (Geitodoris heathi) 🦀🦑

I've got another new paper out this week, this time in Symbiosis! In this paper we use DNA barcoding to describe the diet of the sacoglossan sea slug Elysia diomedea from the Gulf of California, Mexico. Read it here: rdcu.be/ezcoD

Here are a few of the nudibranchs that I was able to film while visiting Komodo National Park in Indonesia earlier this month. #nudibranch #slug #invertebrate #indonesia #scuba 🦑
