This is a tentative ID of a brittlestar rarely found under rocks on Kwajalein Atoll lagoon pinnacles. It resembles those we figure as Ophiomastix sp. 3 but the appears to differ in the sparse spines on the disk and lack of scale-like plates on the arms. It has been suggested that these could be juveniles of Ophiomastix mixta.
