Over several years here in Nevis, I have found (without searching for them) perhaps twenty cushion stars Oreaster reticulatus, of varying sizes with only four rays. They showed no indication of a ray being lost. The seastars appeared bilaterally symmetrical externally - with the exception of the madreporite and anus. I have seen a couple that clearly had lost a ray and were in the stages before regeneration. But I have found so many with four rays and no apparent loss that I wondered if anyone else has seen anything similar.
