Talk:Dichotomous Key/Animalia

From Wikibooks, the open-content textbooks collection

Echinodermata have radial symmetry, and so under this key would be classes as Cnidaria or Ctenophora. I don't know how to fix this, however, without introducing more technical characters.

I made it no longer incorrect, but it is still technical -- not such a big deal, I think, for one of the high level taxa like Animalia. Can always be simplified later... TUF-KAT 18:37, 20 Mar 2004 (UTC)

This is only a superficial symmetry. If one considers e.g. the madreporite, then echinoderms are clearly bilateral symmetric. Lycaon 08:51, 27 November 2005 (UTC)
