Day 4 of OCTO-ber is the greater blue-ringed octopus (Hapalochlaena lunulata). Read more about this octopus's strange mating behaviors in my upcoming book OCTOPUS X. bookshop.org/p/books/octo... PC: Rickard Zerpe/Wikimedia Commons @princetonupress.bsky.social @octonation.bsky.social #books #read

Η Κολομβία στοχεύει να αυξήσει τις γνώσεις της θαλάσσιας βιοποικιλότητας μέσα από νέο κατάλογο ειδών και από την πλατφόρμα του WoRMS. 🪸 www.marinespecies.org/corms/ #Colombia #biodiversity #WoRMS #MolluscaBase #invertebrates #deepsea #fish #marinelife

"Τα καλαμάρια (και παρόμοια είδη) στα πιάτα μας μπορεί να προέρχονται από αλιευτικές δραστηριότητες που συνδέονται με παράνομη αλιεία." 🦑

🐌 Rock-dwelling #Snails face challenging conditions from heat and drought. Could #Shell shape help them cope? New research explores how shell #Morphology varies with #Climate across the Western Palearctic. 1/3

Just a few more days left to send your submission to our ✨photo contest✨ ! We are looking forward to see how molluscs are percieved by your photographic lenses 📷 @wwfgr.bsky.social

Protecting bogs and peatlands is essential for fighting the climate crisis, and also for persevering the species of plants, animals, birds, insects and fungi that rely on them Europe's bogs must be rewetted and rewilded!

New research just dropped today that makes octopuses even weirder than they already are… let me explain🧵🧪🐙🐡🦑

25 years after bottom trawling ended, Chile's seamounts remain damaged. A single trawl can cause irreversible harm – prevention is the most effective strategy. The @fao.org GFCM must learn from this lesson: extend the deep-sea trawl ban to at least 800m. #DefendTheDeep oceana.org/press-releas...

Cool new behavior caught on video! This is a special type of octopus known as a #papernautilus (aka #argonaut) and her shell is a little less than 5cm. Watch as she extends and retracts her fleshy mantle - at the end, she rapidly retracts it all! #blackwater #blackwaterdiving

Marine biologists in Northeast Greenland used an ROV to observe, for the first time in the wild, a mature female bobtail squid (Rossia moelleri) and her egg masses. This Arctic species is present and reproducing even in subzero waters! 🧪 link.springer.com/article/10.1...

This feels like the octopus equivalent of a cat hiding in a pile of laundry. 🐙📷manelor (www.inaturalist.ca/observations...)

Swimming nudibranch 🤩

#MolluscMonday Small (<2 cm) glycymerid bivalve shell with characteristic taxodont dentition. Photographed on a building stone (almost certainly Oligocene Calcaire à astéries) in St Émilion, the famous centre for Bordeaux wine.

🇬🇷 Η Μεσόγειος Θάλασσα είναι ένα hotspot βιοποικιλότητας, με πολλά είδη που ευδοκιμούν μόνο σε εύκρατες ζώνες. Πώς σκεφτόμαστε την προστασία τους; 🇬🇧 The Mediterranean Sea is a hotspot of biodiversity, with many species that thrive in temperate zones. How are we conceiving its protection?

Species discovery is underway in Argentina. Find out more about the latest workshop, bringing together international teams of scientists to discover new species from the South Atlantic oceancensus.org/revealing-th... Thank you to workshop partners @schmidtocean.bsky.social.

Looking forward for some #mollusc news!

I’m most grateful to Robert Cowie at University of Hawaii for reading Daughter of Mother-of-Pearl & writing a blurb for it in Tentacle, Newsletter of the IUCN Species Survival Commission's Mollusc Specialist Group. Wow! 🐌🐌🐌 @graywolfpress.bsky.social www.hawaii.edu/cowielab/Ten...

📷 We are happy to announce that we are organising a ✨photo contest✨ in collaboration with WWF Greece, @wwfgr.bsky.social We are looking forward to discover beautiful pictures of #Molluscs! 🐚 🐙Deadline for submissions - 31st August 2026 🦪

Something we discovered during the last World Congress of Malacology 🤩🐚

And the winner is… Your 2026 International Mollusc of the Year is 𝘾𝙪𝙢𝙞𝙖 𝙞𝙣𝙩𝙚𝙧𝙩𝙚𝙭𝙩𝙖, the Vampire Snail! It will be the first blood-feeding mollusc to ever have its genome sequenced. Huge thanks to the nominators & @sgn.one for unlocking its DNA secrets! 🧬🩸 #IMOY26

Happy Taxonomist Appreciation Day 🧬 It's a big day...Today we’re celebrating the scientists who make sense of life on Earth by discovering, naming, and classifying species. Shout out to all the taxonomists in the Ocean Census Science Network. We're so proud to work alongside you.

Happy International Taxonomist Appreciation Day! 🌍🔬 From the tiniest 🦠 to the most complex 🌱,🪲&🍄, taxonomists are the ones who organize the chaos of the natural world. Go hug a taxonomist! They are really fun-guys & fun-gals 🤗🍄🍄‍🟫 photo credit: @cobusvisagie.bsky.social #fungal26
