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 🦐

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

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)
