This appears to be another small Cycloporus, although that identification is not certain. The small round balls on the dorsal surface could make it a Thysanozoon or Acanthozoon. The photos below show four separate specimens that have some differences but are somewhat united by the small dorsal bumps and smooth wide margins. Three were found under rocks on lagoon reefs while a fourth was on the atoll's seaward reef.
