Colubraria tenera (Gray, 1839)

Colubraria tenera is seen in some references as Colubraria castanea. This species is rather rare in the Marshalls. So far we have seen specimens only on the seaward reef at depths of about 11 to 20m. Like most other species we know, this one parasitizes sleeping fish, usually parrotfish, at night. Also, one specimen was found sucking the blood of a mostly buried stonefish (Synanceia verrucosa) in a seaward reef ledge during the day. The shells reach about 81mm in length.
