Comatula rotalaria, copyright Teresa Zubi.


Belongs within: Articulata.
Contains: Tropiometracea, Antedonacea, Solanocrinitacea, Comasterinae, Capillasterinae.

The Comatulida, feather stars, are a group of crinoids in the larval column has been reduced to a single cirriferous centrodorsal attached to the calyx (Wienberg Rasmussen 1978). They are the most prominent crinoid group in the modern fauna.
