Gibberula cf ovata (Habe, 1951)
5.4mm

This small species is also tentatively identified. It is common at Kwajalein, found under rocks during the day and parasitizing sleeping fish at night. Often clusters of them are found on parrotfish and other fish sleeping on the reef after dark. More information on this parasitic relationship can be found at this link. Formerly, this species was thought to belong to the genus Kogomea.

The photos below show clusters of Kogomea on several different sleeping parrotfish.
