Spring tides have come round again, and I've been out rockpooling for the last two evenings in sunny, calm and beautiful conditions down at Castle Cove.
The stand out highlight was with Iain Outlaw this evening when we found these two gorgeous nudibranchs.
I'm happy that these are Amphorina farrani, which is known to occur in a translucent white form and a purple-black form. A new species for both of us. These two were together under the same rock, and I'll pop them back there on tomorrow's low tide.
Solar-powered Sea-slug Elysia viridis
Mystery organism. Suspected egg-sacs.
As well as lots of Grantia compressa and Clathrina cf. lacunosa, I realised there is a third species of tiny basket sponge under the boulders, which I've identified as Clathrina coriacea. Under the compound microscope, the sponge is composed entirely of triradiate spicules.
