Polycera quadrilineata or Four-lined Polycera. A small but relatively common nudibranch found in rockpools and along piers and pontoons, if you have the patience to sift through the wracks. #Nudibranch #MarineLife #Polycera #Rockpool #Tidepools #Shetland #VisitShetland #SeaLife #Wildlife #Nature

Some highlights from recent Rockpool Safaris. IDs in Alt text.

Solar-powered Sea Slug - Elysia viridis, from a Rockpool in Shetland. Flashing part of its "solar panel" that is filled with chlorophyll harvested from the algae it grazes on. #Rockpool #Tidepool #Nature #Shetland #Wildlife #SeaSlug #Nudibranch #MarineLife

A lovely evening Safari with 7 entrepid rockpool explorers. We found some of the largest Sea Lemons I've ever seen, and a great selection of other intertidal beasties from Sea Stars to Squat Lobsters. #SeaLemon #Nudibranch #Rockpool #Tidepool #MarineLife #Nature #Wildlife

European Cowrie or Groatie Buckie in Shetland dialect. So much more interesting like this than the dead shells you might find on the beach! #Cowrie #MarineLife #SeaSide #Rockpool #Tidepool #Nature

I recently posted this as Cadlina laevis (White Sea Slug) but on review think it might be Jorunna tomentosa. If anyone on here knows and can talk me through the ID I'd really appreciate it! #Nudibranch #Shetland #MarineLife #Rockpool #Tidepool #Nature #Wildlife

Elysia viridis - Solar-powered Sea Slug This fascinating little creature ingests chloroplasts from its food algae, then uses them for photosynthesis to supplement its food supply. The folds on its back fan out to increase surface area to aid this process. #SeaSlug #Shetland #Rockpool #MarineLife

Some recent Nudibranch finds whilst rockpooling around Shetland. Identifications in Alt text. The variety, colour and alien-ness of Nudibranchs never ceased to amaze me! #Shetland #Rockpool #Tidepool #SeaSlug #Nudibranch #Seashore #MarineLife #UkWildlife #ShetlandWildlife #Nature
