Comatulidae is a family of comatulid crinoids. Since 2015, it replaces the family Comasteridae. [1]

Description and characteristics

This family is of recent restoration, and still has no consensual description. However the description of the family Comasteridae remains partially valid.

This family counts between 93 and 95 species, distributed in 21 genera, [2] which makes it the second most diversified family of crinoids the behind Antedonidae, representing approximately 1/6th of known crinoid species. It contains most of the big species of shallow tropical feather stars, in particular in the Indo-Pacific. [2]

List of genera

This family has been recently restored following genetic works from Charles Messing's team. [2]

It contains the following genera: [1]

Articulata are a subclass or superorder within the class Crinoidea, including all living crinoid species. They are commonly known as sea lilies or feather stars. The Articulata are differentiated from the extinct subclasses by their lack of an anal plate in the adult stage and the presence of an entoneural system. Articulata first appeared in the fossil record during the Triassic period although other, now extinct crinoid groups, originated in the Ordovician.

Davidaster is a genus of crinoids. According to the World Register of Marine Species, a number of species that originally were included in the genus Nemaster are now included in Davidaster.

The primary comb has the teeth widely separated and confluent with the lateral edge of the segment.
