Phormosomatidae

Phormosomatidae is a family of echinoderms belonging to the order Echinothurioida.
The family was described in 1934 by Ole [Theodor Jensen Mortensen].
Species from the family Phormosomatidae are found in both the Indo-Pacific and the Atlantic.
Species from this family are distinguished from the Echinothuriidae, by their polyporous ambulacral plates, their adoral spines which lack a terminal 'hoof' and acuminate teeth, but have a lantern which is similar to species of the Echinothuriidae.
