It's always great to see more marine species being posted. Where did you find it - what was it on substrate-wise?
It was in the Laminaria zone & on a Laminaria digitata blade.(& more recently found several, also on Laminaria)
I'll have to have to keep an eye out for them next time I'm at the coast, they're very easy to overlook!
