Such a perfect ending for a paper!

"The animals themselves did not long survive in the aquarium. A slow process of dissolution set in at some point on the body, and gradually more and more of the tissue melted away till only the tentacle- and brain-region remained. This crept about for a few days, but finally it, too, disintegrated. THE UNIVERSITY OF CHICAGO, May 12, 1893."

Wheeler, W. M. (1894). Journal of Morphology, 9(2), 195–201. doi:10.1002/jmor.1050090203

New paper from Ikeda et al. on the biogenesis of chitin bristles in the annelid #Platynereis with nice #vEM reconstructions and a chitin synthase knockout. (cdn.masto.host)

Beautiful new study by Michael Bok, Macali & Garm on the high-resolution eyes of the enigmatic alciopid annelids, from Ponza island. (cdn.masto.host)
 

Beautiful new study by Michael Bok, Macali & Garm on the high-resolution eyes of the enigmatic alciopid annelids, from Ponza island.
"Our results show that the eyes of alciopids possess the anatomical, morphological, and physiological properties requisite for high resolution tasks and object vision"

Press release at @eLife of our paper exploring the mechanism of pressure sensing by UV light sensors in #Platynereis larvae in c/biology@mander.xyz

@Sal Thank you! Indeed, the opsin is not the sensor, but we can use a mutation in the opsin gene to disrupt the ciliary superstructure and then we see a phenotype in pressure sensing, and also in UV light sensing, as we previously described: https://elifesciences.org/articles/36440

We have now published a new and massively extended/reworked preprint of the whole-body #Platynereis larval #connectome with over 50 figures in c/biology@mander.xyz

@dpunked Thank you! A bryozoan larva would be nice! Maybe one day we will get there...
