I haven't seen mine done it. But, i was told by LFS that brittle star can reproduce into a new brittle star from broken arm parts.

Found this info. Asexual reproduction confirmed...

Behavior of brittle stars
As the name suggests, the arms of the brittle stars are rather liable to break. This is actually an escape mechanism. Those arms regenerate quickly and an entire new organism can regenerate, if the broken arm is attached to a seizable portion of the disk. Brittle stars can reproduce asexually by self-division. Brittle stars are the most active and fastest moving echinoderms.

Brittle stars feed on plankton but also on detritus, coral-shed mucus, bottom detritus (detritus = organically enriched film that covers rocks), mollusks and worms.
