Greene's triggerfish

Xanthichthys greenei, also known as the Kiri triggerfish, is a relatively new species of triggerfish first identified in 2005 from Kiritimati (Christmas Island) atoll, Kiribati. It is abundant on coral rubble and holes adjacent to deeper drop-offs at several localities of the coasts of Kiritimati. It has always been observed near the reef substratum, where it would seek shelter when approached.
