#molluscmonday with piping fresh mollusc photos from the weekend, this time we got the Velvet dorid (Jorunna tomentosa) as our featured species, this is one of the larger species found in Sweden, so often quite easy to spot.

Found an amber snail estivating at the farmers market. It would probably have ended up crushed where it was, so I gently detached it and chucked it into thick brush by the river.

Amber snails are fairly common land snails but this is the first living one I've ever seen.

Today I made my 2,000th observation on iNaturalist. While working at the allotment garden, this black-velvet leatherleaf slug popped out of a clump of weeds. They are invasive in Alabama and are slowly working their way north.

It was the first one I've seen in person, and I was bith excited and a bit dissapointed that they're in my area now. #Gardening #MolluskMonday #MolluscMonday #Nature
