`Unique phenomena are important in history but are difficult to study because they resist categorization and are therefore unpredictable. To examine the timing and circumstances of unique evolutionary events, we identified traits that evolved only once in the highly diverse phylum Mollusca as well as unique first occurrences of traits that evolved repeatedly since.`

In #SouthAustralia #Coorong there are beaches along the brackish lake almost entirely made up of tiny (5mm long) #mollusc shells. They are not a result of any recent toxicity but have accumulated over a long time
Tiny #shells collected from the beaches of Rottnest Island decades ago last century, held within my grandfather’s gilded #brass cigarette case. #nature #mollusc #vintage #collection #treasures A world in the palm of your hand.

A mollusc themed repeat pattern for your nature loving Valentine featuring three of my #linocut heart cockles (Corculum cardissa). Perfect for your favourite malachologist, beach comber or shell collector.

Corculum cardissa, the heart cockle, is a species of marine bivalve mollusc in the family Cardiidae found in the Indo-Pacific. If viewed from the side, it looks like a heart. 🧵

everyone has heard of the Pacific Northwest Tree Octopus, a joke made up for a poorly-thought out survey of what 1990s people believed on the internet, but somehow nobody has heard of the Mangrove Jingle Shell Clam, a real and amazing animal I learned about from @KateShaw

hopefully Dr. Dan Killam @dantheclamman can provide us all with more information on this animal.

Belgium, Wemmel : Two-lipped Door Snail ( Clausiliidae, Alinda biplicata) #belgium #wemmel #mollusc #snail #animal #alindabiplicata

Here's a sample of what I've been working on during the last months: creating overview pictures of different types of gastropod (and bivalve) shells for my professor. This one's called Epitonium clathrus.

My attempt at a snail, carved in lime wood, I think. Inspired by lissachatina fulica, the giant African land snail. #woodcarving #mollusc

I follow this rad #engineering dude on YouTube because he shares really cool & interesting content. I love this recent video where he bought an #octopus from a seafood market, brought it home & taught it how to play an underwater #piano that he invented.
