#mollusks — Public Fediverse posts

💁🏻‍♀️ TIL: 🦪🌡️ A #Stanford led study explains why #clams and #snails dominate modern shorelines while #brachiopods barely survived the #GreatDying.

Researchers measured #oxygen consumption in living #animals to show that slower metabolisms could not cope with warming, oxygen depleted waters 252 million years ago. The authors warn that today’s warming #oceans could trigger a similar ecological shift.

(Posting in my personal capacity.) Journalist Steve Baragona was so invested in shooting
river-cleaning #mussels that he ended up falling into the mud. Don’t worry! He is fine and our story about these important #mollusks is coming out later this week. Stayed tuned! We cover #environment and #science . Follow us on social media platforms.

#Snails are primarily marine #mollusks. According to current hypotheses, the #sistergroup might be #Cephalopoda plus #Scaphopoda (Link below) . One #Apomorphy, i.e. evolutionary new acquisitions of the stemspecies, is the #asymmetrical #shell that is wound in one direction, which is due to a #torsion of the #mantle and visceral sac.
The species in my #photos is #Cornu #aspersum from Italy. #biodiversity,
