WebSea spiders (Pycnogonida) are a marine arthropod lineage that forms the sister group of all other extant chelicerates. Despite this interesting phylogenetic position and the virtually ubiquitous occurrence of pycnogonids in benthic communities across the world’s oceans, their biology, taxonomy, phylogeny and evolution remains poorly studied. WebFlatworms were the sister group, or consistently basal, to the other lophotrochozoan clade that included dicyemids, annelids, molluscs, and brachiopods. Dicyemid mesozoans (phylum Dicyemida) are endoparasites, or endosymbionts, found only in the renal sac of benthic cephalopod molluscs.
