It seems in all our years in the Marshalls, we personally got only a single photo of Heteropriacanthus cruentatus from Kwajalein. We are not sure if this represents rarity, or if we simply did not distinguish them sufficiently from its similar and apparently more common cousin, Priacanthus hamrur. One of the ways to distinguish the two species is that H. cruentatus has a slightly convex tail fin, while that of P. hamrur is distinctly lunate (concave). The one photo was taken in a seaward reef channel small cave.
The two photos below were taken by Jay Lord in a cave on the steep seaward slope of Kwajalein Atoll.
