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 @alicerouan.bsky.social @NorioMiyamoto

Join the best invertebrate event of 2025! The official website for the 6th International Congress on Invertebrate Morphology (ICIM6) is now live! Check it out: icim6.com Thank you Felipe and colleagues for hosting this!

Our paper describing the second species of Micrognathozoa, Limnognathia desmeti, is out: doi.org/10.1098/rspb... - big thanks to all coauthors, to Willem H. De Smet for finding this species, and to the Villum Foundation a.o. for supporting this project!

Big congrats to Jan Raeker and collaborators on this great paper: doi.org/10.1016/j.ym... The crowning glory moment of Jan's PhD :-) presenting an exiting phylogenomic study of Priapulida (penis worms) with unexpected predictions:

We looked into details of the stem cell system of catenulids. Surprisingly, it was very different from the canonical neoblast-based systems of other flatworms. What does it tell about the evolution of stem cells and regeneration? Check in our latest paper in @naturecomms.bsky.social: bit.ly/3WK2ZzR

Join the "Zoomorphology & Evolution Meeting" at Dep. of Biology, UCPH, 13-19:30, 7 March 2025 Best wishes Katrine Worsaae & Peter Funch

Join Denmark's excellent community of zoomorphologists and evolutionary biologists for a day of stimulating talks, networking, and discussions! Let us know if you will participate and maybe give a talk, on your research or ’cool methods/facilities’ 🔬
