See text Comatulidae is a family of comatulid crinoids.

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