The ammonites' graveyard: https://shutterbugofstone.blogspot.com/2025/08/the-ammonites-graveyard.html

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.

Another week another #molluscmonday
This week i got to photograph a for me new species, the Crystal Seaslug (Antiopella cristata), and i have to admit it is one of the prettiest nudibranchs 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

#molluscmonday is here, and i got piping fresh nudibranch photos from this weekend's dives, these are Orange brown aeolids (Aeolidiella glauca), the most common of nudibranchs in Sweden, but they are nice nonetheless :D

Some ammonites (for example, this Kosmoceras jasoni) crushed shell in shale for #molluscmonday displayed sexual dimorphism, where the female (macroconch) of the species was larger than the male (microconch). It is thought that this was so the female could accommodate a brood of eggs within the shell.

Collected the #bivalve Bositra buchii for #molluscmonday only a few millimetres across I find them really fascinating. It was proposed that they were bysally attached to floating organic matter the so-called "pendant" life habit. An abundant species found at many horizons within the Oxford Clay.

Picked up another aesthetic crushed shell in shale Kosmo eras #ammonite from the Callovian ( Middle Jurassic ) for #molluscmonday with bositra buchi #bivalves nestled beside it.

Here's an interesting photograph for #MolluscMonday A Hoof-shield Limpet. 2nd photo is a zoomed in version of the first one, but I might have managed to photograph a limpet laying eggs. #ShoreWalk #Photography #虫 #EggCells #Nature #Invertebrate

While going through my latest bag of shells collected during field work, I found two living Stenotrema (aka slitmouths), probably S. barbatum (aka Bristled Slitmouth).

I've placed them temporarily into a container with some snakewort and walking fern while I decide whether to release them or keep them in a little terrarium. #snails #gastropoda #MolluscMonday #MolluskMonday #terrarium

Got a new paper for #MolluscMonday!
With Marijn Roosen and Bram Breure.

This is 'Part 3' of an ongoing revision of the Scolodontidae, a family of (largely) carnivorous land snails from Central and South Americas.

Daedalochila troostiana, commonly called the Nashville Liptooth, is a relatively rare snail that has a beautifu shell. Found in Madison County, Alabama.

Hmm, looks like a Bladetooth, or maybe any wedgetooth snail, Patera or Xolotrema? I need to brush up on my southern Appalachian land snails.

I love the slight keel along the shell whorl and the prominent denticles.

We have 2 new species of freshwater snails for this #MolluscMonday, named after some of our favourite #LOTR characters.
