Classification Myzostomida have apparent morphological affinities to Polychaeta, and have been treated as a group within Phyllodocida. The position of Myzostomida is unresolved and recent molecular studies have not placed Myzostomida close to Polychaeta (uncertain if real or artifactual placement), although authors find similarities (just for example their planktonic larvae look very polychaete like). Myzostomida are placed in Annelida based on mitochondrial gene orders (Mwinyi et al. 2009). Most recently Bleidorn et al (2014) wrote "Placing the myzostomids in the Annelida is the best supported and most plausible hypothesis in the light of the current data"However, there have been contrary views. As recently as 2000 it was concluded (Eeckhaut et al, 2000) that "analyses strongly reject the grouping of myzostomids with any subgroup of annelids.This does not really conflict with morphological data because, although myzostomids are most often considered as polychaete annelids, not a single morphological synapomorphy (i.e. a shared derived character state) linking the two taxa has been unambiguously identified. Indeed, the character states usually put forward for grouping myzostomids and polychaetes (the presence of chaetae and a trochophore larva) are encountered in other spiralian groups: chaetae occur in the Clitellata, Pogonophora, Echiura, and some Mollusca and Brachiopoda (Specht 1988), and trochophores are found in the development of some Mollusca, Sipuncula, Echiura and Pogonophora (Heimler 1987). " As recently as 2007 (Wagin, 2007) the Myzostomida were raised to a separate phylum status. This appears to be the only publication ever to treat myzostomids at phylum-level. Wagin (2007) was a posthumous publication some twenty years after his death [details] Ecology Most Myzostomida are free-living associates of crinoid echinoderms. Some are encysted by the host in galls, some are endoparasitic. Others live on basket-stars, asteroids, or ophiuroids. Jumars et al (2015:A169) have further family-level feeding analysis [details] |
