A few stills from my afternoon session with these Grey Sea Slugs.

At first I thought I'd found one of the other similar species when spying the paler one, but it's Y marking on its head confirms Aeolidia papillosa.

It's #SeaSlugDay, you say? Have a Grey Sea Slug (a travesty of an English misnomer for Aeolidia papillosa) busily eating alive a hapless Beadlet Anemone that, short-changed by evolution, couldn't run away from it. Nature red in tooth and claw (and wobbly stuff) in a rockpool on #Shetland in 2021.

This is what they would look like in the squid universe if anybody was wondering. And yes, the band would be called Seacolourgirl.

Aeolidia. But at what cost? (There's no cost it's just fun to say "Aeolidia, but at what cost?)

Yes it's Aeolidia papillosa, the common grey seaslug, from the UK, whose name totally doesn't match with its cuteness! It's also called the shaggy rug nudibranch.

I found this nudibranch (Aeolidia papillosa) on a dive at the UNH Research Pier in New Castle, New Hampshire.

Shag rug nudibranch ('sea slug') - Aeolidia papillosa! I saw this unusually pink individual last month during the solstice tidepooling event run by Cal. Academy. Nudi spotted by
Alison Kestrel. About 20mm long or so. 📸Olympus TG6. Half Moon Bay, CA.
