Asteroidea - Asteriidae
If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

Ambulacra compressed, podial pores quadriserial, strongly offset; first 4 or possible 5 adambulacrals forming adoral carinae; adambulacra with transverse series of 4 spines; large uncrossed clam-shaped pedicellariae present on dorsal surface only; dorsal surface with numerous stout spines, especially on disk and carinal series.|
