Distinguishing features

The genus Zygometra is differentiated from other crinoids by a particular type of articulation (a syzygy) in the first division series. This character is virtually impossible to determine in the field. All Zygometra species have strong spines on the distal cirrus segments.

Zygometra punctata is a small crinoid with up to about 20 arms and a good ring of short, stout cirri. Colour appears to vary widely but arms are usually banded.
