Spatangoida
The heart urchins or Spatangoida are an order of sea urchins. Their body is a somewhat elongated oval in form, and is distinguished by the mouth being placed towards one end of the animal, and the anus towards the other. As a result, heart urchins, unlike most other sea urchins, are bilaterally symmetrical, and have a distinct anterior surface. The presence and position of the mouth and anus typically give members of this group the distinct "heart" shape from which they get their name. Heart urchins have no feeding lantern, and often have petaloids sunk into grooves. They are a relatively diverse order, with a number of varying species.

Asterostomatidae
''Asterostomatidae'' is an extinct family of sea urchins belonging to the order Spatangoida. They are slow-moving, shallow infaunal, or sediment-dwelling organisms, and are deposit feeders or detritivores.

Aeropsidae
Aeropsidae is a family of echinoderms belonging to the order Spatangoida. It contains one extant genus. There are also eight extinct genera, most of which fall in the subfamily Corasterinae. History Initially, a large number of genera were included on the basis of their apetaloid Ambulacrum (anatomy), ambulacra. This, however, resulted in the inclusion of a number of unrelated genera some of which are Holasteridae, holasteroid, and others that are Spatangidae, spatangoid. Later, Mortensen included just two genera - ''Aceste'' and ''Aeropsis''. The two forms are very different in test architecture. Aceste is now considered to be an apetaloid derivative of ''Proraster'' and is nor believed to be closely related to Aeropsidae. Genera The following genera are recognised: Subfamily Corasterinae Lambert & Thiéry, 1924 * † ''Coraster'' Cotteau, 1887 * † ''Cordastrum'' Nisiyama, 1968 * † ''Cottreaucorys'' Lambert, 1920 * † ''Homoeaster'' Pomel, 1883 * † ''Lambertiaster'' G ...
