Cuthona sibogae (Bergh, 1905)
Cuthona sibogae is another small species and has been found in the Marshalls at Enewetak, Utirik, and Kwajalein Atolls. The first time we saw them, there were more than 25 specimens in a softball-sized mass of hydroid tentatively identified as Dynamena crisoides Lamouroux, 1824. Since then we have seen just one or two at a time on lagoon pinnacles or the seaward reef. Measured specimens ranged from 7 to 10mm.


This was a portion of the hydroid colony where we first found Cuthona sibogae.
