I think this article needs a lot of help- I am not a biologist, and hemichordates are not really my area of interest as an amateur- but I thought it had been reasonably well established with molecular data that hemichordates are monophyletic, and sister to echinodermata as ambulacraria, and that the main taxonomic controversy remaining was whether pterobranchia is really a sister group to enteropneusta, or whether enteropneusta is paraphyletic. Any biologists wish to comment.


Except that marine worm is far more general, and pterobranch is more specific. Please be careful with this stuff! --Josh Grosse

I'm just copying over what was in metazoa. I plan on checking out all the facts later - and in the meantime have placed each one of these on my watchlist. Pardon the mess. :) --maveric149

1. Taxobox says EnterEpneusta, but the article says EnterOpneusta. What is true? 2. What are Planctosphaeroidea?--213.247.213.207 21:19, 11 February 2006 (UTC)
