Enjoyable rockpooling in Scilly this week, the highlight being this superb Polycera quadrilineata which performed beautifully for our safari group #ScillyRockpools #Nudibranchs 🦑

This little orange #Nudibranch had been previously ID’d as Polycera abei - but is now more likely to be an undescribed Polycera. This one is about 7mm long and was found in Bali.

A photo of a small sea slug that is bright orange in colour. It’s rhinophores and gills are dusky black. It also has black spikes along its lateral mantle line and on top of its body. It also has some white projections within the mantle line.

Spring sea slugs - so many around at the moment. The once rare rainbow #seaslugs are becoming quite common, more Polycera around than I’ve seen before, my second ever disco Doris. Here’s some recent clips
- a teaser before something bigger out next week…

I might still be Suffering(tm) from this course of antibiotics, but the #nudivember entries continue with Polycera tricolor, which my brain desperately wants to be Polycera tricolour.
