This is Calappa, the same crab that I made a pumpkin of (next skeet) and one of bluesky's favorite crabs. Not only does it run funny, it has an adorable face and its claws are specialized like a can opener for snails 🦀🦑

We’ve uncovered a new species of snake! 🐍 Paradoxophidion richardoweni lived 37 million years ago and has a strange mix of features that suggest it's an early caenophidian, the group containing 80% of living snakes. Discover what it reveals about snake evolution 👇 www.nhm.ac.uk/discover/new...

#FossilFriday Not to be outdone by Isaac Newton who is buried beneath a gastropod fossil in Westminster Abbey, the famous geologist Charles Lyell’s gravestone is Carboniferous crinoidal limestone full of columnals of these ‘sea-lilies’.

After a quick search, it appears that "Sally the pet seal" has never been mentioned on here Bluesky, so let me fill in this shocking oversight.

The global whaling industry experienced a boom c. 1840-1950 as technology allowed whalers to hunt the Southern Ocean around Antarctica. Under standard models, we would have expected krill populations to have *exploded*. Instead, they DROPPED exponentially. Let's talk about the KRILL PARADOX.

🐌 For this week’s #MolluskMonday, a new rabbit hole I just discovered : there’s a whole « African giant snail-gram », where these big bois (Lissachatina fulica) are getting over-pampered with optimal humidity, calcium-rich diets, and cozy terrariums…

And you, how’s science popularization in your country? On French YouTube, Léo from Dirty Biology (1.17M subs) challenges Gordon Childe’s early 20th‑c. evolutionism and Rousseau’s “state of nature,” using AI‑generated visuals. You can imagine my face when I saw his Florida “shell mounds”... 🧪 🏺

Very cool finding ! Not only is it the oldest shell-working workshop for beads and shell adornments, but at that time the sea was more than 100km away 🤯 🏺 🦑
