I’m happy to share some plugins I’ve been developping this summer: "Channels and Contrast" and LUTs Manager!
I can’t find new bugs and ideas by now so I need your help to please test them in your machines and report bugs, feedbacks and ideas! forum.image.sc/t/looking-fo...

Today's cool museum collection discovery: Bryozoans growing on crustaceans!

I believe this ctenostome belongs to the genus Triticella, which is known to grow on specific groups of marine invertebrates 🦐

Last month, the English version of Hans de Blauwe's great book on North Sea bryozoans was released. Find excellent information on local species and identification keys.

Marine and Brackish Bryozoans from the Southern Bight of the North Sea
This book is a reliable reference for professional bryozoologists and keen amateur naturalists studying northern European bryozoans, including 200 species.

Boring bivalves are actually quite interesting! The ability to bore into rock has evolved multiple times in bivalves. @spissatella.bsky.social found that boring bivalves have a greater variety of forms than their non-boring counterparts! (220)

New addition to the spectacular life cycle of Osedax worms: sex of O. japonicus is genetically (not environmentally) determined since larvae show both morphological and transcriptomic signatures of gender. Might help us explain male dwarfism rdcu.be/eCHBe

In two independent collaborations with two different labs (Leonardi-lab Argentinia, and Gorb-lab Germany) new data on different seal lice and their adaptations for underwater respiration. See more here:

Host-parasite coevolution leads to underwater respiratory adaptations in extreme diving insects, seal lice (Lepidophthirus macrorhini) - Communications Biology
Seal lice survive deep-sea dives by closing spiracles, reducing oxygen use, and breathing through their skin. Genomic data suggest they store oxygen via haemoglobin, showing insects can adapt to extre...

P is for Patagurus, a hermit crab known from only ONE SPECIMEN EVER!

Instead of a snail shell, it wears a bivalve to cover its tiny abdomen. Is this how hermit crabs gave up their houses in carcinization? 🤔 (see king & coconut crabs, ALSO hermits)

On the final day of 2024, first data on growth rates from boring bryozoans of the genus Immergentia. Great work from Mildred Johnson and other colleagues.

Boring bryozoans dissolve calcium carbonate substrates, leaving unique borehole traces. Depending on the shell type, borehole apertures and colony morphology can be diagnostic for distinguishing taxa,...
