@Sedathems it's about a polyclad flatworm, related to this beauty

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).

New paper from Ikeda et al. on the biogenesis of chitin bristles in the annelid [#Platynereis](https://biologists.social/tags/Platynereis) with nice [#vEM](https://biologists.social/tags/vEM) reconstructions and a chitin synthase knockout. Bristles are formed in a process of biological 3D printing.

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" [https://doi.org/10.1016/j.cub.2024.02.055](https://doi.org/10.1016/j.cub.2024.02.055) [\#annelid](https://biologists.social/tags/annelid) [#Evolution](https://biologists.social/tags/Evolution) [#eye](https://biologists.social/tags/eye) [@biology](https://mander.xyz/c/biology) [@mikebok](https://ecoevo.social/@mikebok)

@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](https://biologists.social/tags/Platynereis) larval [#connectome](https://biologists.social/tags/connectome) with over 50 figures [https://www.biorxiv.org/content/10.1101/2024.03.17.585258v1](https://www.biorxiv.org/content/10.1101/2024.03.17.585258v1) All the analyses, plots and figures should be reproducible in [#rstats](https://biologists.social/tags/rstats) with the code provided: [https://zenodo.org/doi/10.5281/zenodo.10825370](https://zenodo.org/doi/10.5281/zenodo.10825370) [@zenodo\_org](https://bird.makeup/users/zenodo_org) by querying our public [#CATMAID](https://biologists.social/tags/CATMAID) database: [https://catmaid.jekelylab.ex.ac.uk](https://catmaid.jekelylab.ex.ac.uk) [\#neuroscience](https://biologists.social/tags/neuroscience) [@biology](https://mander.xyz/c/biology) [#volumeEM](https://biologists.social/tags/volumeEM) [@biorxivpreprint](https://biologists.social/@biorxivpreprint)
Press release at [@eLife](https://fediscience.org/@eLife) of our paper exploring the mechanism of pressure sensing by UV light sensors in [#Platynereis](https://biologists.social/tags/Platynereis) larvae [https://elifesciences.org/for-the-press/5f58b93c/plankton-use-uv-light-sensors-to-detect-pressure-change-and-avoid-getting-swept-away](https://elifesciences.org/for-the-press/5f58b93c/plankton-use-uv-light-sensors-to-detect-pressure-change-and-avoid-getting-swept-away) Luis Alberto Bezares Calderón et al. paper here: [https://elifesciences.org/reviewed-preprints/94306](https://elifesciences.org/reviewed-preprints/94306) [\#neuroscience](https://biologists.social/tags/neuroscience) [#cilia](https://biologists.social/tags/cilia) [#zooplankton](https://biologists.social/tags/zooplankton) [#science](https://biologists.social/tags/science) [@biology](https://mander.xyz/c/biology)
Interesting review by Maria Sachkova on the [#ctenophore](https://biologists.social/tags/ctenophore) nervous system and the challenges of studying it.
