The ruby snapper is one of 103 species in the Lutjanidae family. This species can be found in the deeper (up to 400m) waters of the Indo-Pacific including Hawaii. Fish that are associated with deep water habitats will typically have dark or red coloration and large eyes in proportion to the head. As snappers go, the ruby snapper has particularly large eyes giving it the ability to capture more light at depth and successfully hunt it’s prey of squids, shrimps and crabs. The largest ruby snapper to date was a male over 4 feet long. A similar species that is sometimes confused with the ruby snapper is the flame snapper.
