These may be Boloceroides mcmurrichi, but since the tentacle arrangement looked different and a lot more dense, we decided to treat it separately. The upper one was on a piece of dead fungiid coral on a southern Kwajalein Atoll lagoon pinnacle, and the lower one was in a lagoon Halimeda patch. Both were somewhat larger than typical B. mcmurrichi.
