Flatworm cocoons in the abyss: same plan under pressure

This study provides the deepest record for free-living flatworms and the first information on their early life stages in the abyssal zone, which were very similar to those in shallow-water forms. This similarity in development between the relatively benign shallow-water and the extreme abyssal environments suggests that triclads adapting to the latter faced primarily physiological and/or ecological adaptive challenges rather than developmental ones.PMID:38263880 | PMC:PMC10806396 | DOI:10.1098/rsbl.2023.0506
