I'm pretty sure SOME chelicerae are opposable and act as pincers.

[edit] New Mandibulata subphylum

If Chelicerata get their own article, I think Mandibulata should as well to encompass the crustaceas, myripodas, and insectas. —Preceding unsigned comment added by 99.229.128.125 (talk) 20:09, 21 October 2007 (UTC)

[edit] Tetraconata and Myriochelata are here to stay

As of April 2008, it seems most probable that (Hexopoda + Crustacea) will be paired off against (Chelicerata (with Pycnogonida) + Myriopoda). The group that would unite myriopods (centipeds and millipeds) with hexopods (to the exclusion of chelicerates) was not recovered in moleclar studies.

This means that Mandibulata is out, as a discarded hypothesis, but we should not worry. The Arthropoda surely have more surprises in store for us.--Wloveral (talk) 04:41, 1 May 2008 (UTC)
