In Sclerasterias, fissiparity seems to be confined to very young individuals.

Active fissiparity seems to be correlated with 6 arms and 4 madreporites.

In echinoderms, this method of reproduction is usually known as fissiparity.

Despite this, they don't reproduce asexually (by fissiparity) during the summer months.

These young individuals often undergo fissiparity.

In echinoderms, the process is usually known as fissiparity (a term also used infrequently for fission in general).

Sunflower seastars can reproduce either asexually through fissiparity or sexually through broadcast spawning.

Some brittle stars, such as the six-armed members of the family Ophiactidae, exhibit fissiparity (division though fission), with the disk splitting in half.

A lack of any juvenile or young specimens found leads to the view that there is no larval recruitment and that this species only reproduces by fissiparity.

Fissiparity in the starfish family Asteriidae is confined to the genera Coscinasterias, Stephanasterias and Sclerasterias.

It can reproduce itself by fissiparity (self division), being capable of regenerating even one arm into a whole new body, but only if the arm includes part of the central disc.
