Nudibranchs / Sea Slugs
There's no common name for this colourful slug, Eubranchus tricolor. This picture was taken in Lochcarron in NW Scotland. At certain times, and they don't appear to be the same every year these slugs can be found in abundance. This picture was taken with a Nikon D500, using a Nikon 105 mm VR and Iron Z240 strobes.
