Good Friday - Mollusc Magic

Had a nice wander around at low tide on Friday with some new mollusc action. First I was amazed when I looked down at a small pool in the sand to see a squirt of water break the surface. On closer inspection I found a scallop which when picked up tried to swim off (in the open air - didn't work). I tried to persuade it to swim after that but it was having none of it.

Next up an overturned rock produced a Grey Sea Slug which was a great addition. But it wasn't over as it seems a peculiar looking collection of eggs in a spiral ribbon appear to be Sea Lemon eggs. I still need to confirm that this is a structure unique to the species but the implication in Collins is that it is.

A few other bits and pieces were picked up over the weekend, not least the new-for-county hoverfly Platycheirus ambiguus, the males of which were loosely swarming over the flowering blackthorn.This is my third addition to the county Platycheirus catalogue.
