Recently reminded of this amazing MUREX in situ video! Predation or scavenging? #molluscmonday youtu.be/7r1i2WzlijY?...

#molluscmonday !
A dreamshell just arrived!
Zonaria angolensis (31.7 mm, Farol das Lagostas, Angola). This very rare cowrie completes my Zonaria collection!

New paper out for #MolluscMonday.
A review of one of Brazil's oddball snail species, 𝘌𝘱𝘪𝘱𝘩𝘳𝘢𝘨𝘮𝘰𝘱𝘩𝘰𝘳𝘢 𝘴𝘦𝘮𝘪𝘤𝘭𝘢𝘶𝘴𝘢, from the southernmost reaches of the Atlantic Forest.

#molluscmonday again! And we are featuring something that is not a nudibranch this time. The Spotted sea-hare (Aplysia punctata). Fun fact, this one can spit ink to scare away predators, like a cephalopod 🤿🦑

#MolluscMonday: the Early Jurassic ammonite Psiloceras planorbis from Watchet on the Somerset coast, a locality visited by Mary Anning in 1832 (this is not one of her specimens, although she would have been familiar with these fossils and their iridescent shells).

#MolluscMonday Giants from the south. A display cabinet in the Sedgwick Museum, Cambridge houses huge rudists from the Upper Greensand (Albian) of Shillington, Bedfordshire, an unexpected occurrence in the British Cretaceous far away from the Tethyan homeland of these bivalves.

When I travel, I always check out the seafood section in the grocery stores. Here are some New Zealand green-lipped mussels for #MolluscMonday. #MarineLife #MolluskMonday 🦑🌊

In 1962 David Raup used an IBM 7090 and a plotter to turn four numbers into snails. Turn one dial, translation, and a flat ramshorn coil becomes a planospiral snail becomes a tower shell. 🧪🐌 #MolluscMonday #SciArt

For this #molluscmonday we got a large one, the Tritonia hombergii. This sea slug grows to about 20 cm, which is gigantic compared to most other species in Sweden.

#MolluscMonday: spotted this clam shell decoration on a visit yesterday to Newhailes, cared for by the National Trust for Scotland. Thought at first that they were moulded plaster but they’re real, gilded, clam shells from 1816 or earlier.

#MolluscMonday Scratched by the feet of countless visitors unaware of its existence, a Carboniferous gastropod in a memorial stone in the cloisters of Westminster Abbey.

Here's a new contribution to #MolluscMonday :)

More geekery tonight. Trying to make sure my code worked as intended and generating Raup's Figure 2 from his 1962 paper "Computer as Aid in Describing Form in Gastropod Shells" #marinelife #SciArt #paleobiology #MolluscMonday #paleontology

Finally got around to making Raup's mollusk shell model work in R. Also spent too much time trying to give a retro look. #marinelife #molluscmonday

*Megathura* for #MolluskMonday! 🌊🦑 #MarineLife #MolluscMonday

#molluscmonday !
I just received some gorgeous Vietnamese Amphidromus. The larger specimen (A. heinrichhuberi) measures 60 mm. The pair of smaller ones (A. jomi) is named after a friend.

Two further slit shells, Pleurotamariids from Puerto Rico, 283m or thereabouts, Vieques Island seen by #Okeanos in 2018 during the Oceando Profundo expedition #molluscmonday

Terrific example of #scicomm for my #ENVSCOMM26 students to watch & learn, about the Billion Oyster Project in NYC, which aims to replenish oyster reef there for all of the good reason. Also thematically apt for #MolluscMonday! 🧪🦪
