Life can be quirky. That sliding doors moment when I decided to not do biology at school - and have regretted it ever since. I now find myself 38 years later about to collaborate as a citizen scientist with a post-doc researcher on collecting and naming some Nudibranch. 2026 seems suddenly brighter.

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) 🦀🦑
