Description

Blue-and-gold snapper has an oblong body. The pointed snout has front and rear nostrils which are simple holes. It has a relatively large mouth which has protractile jaws. The teeth are conical to canine like in shape, with the front teeth typically enlarged so that they resemble fangs. The vomerine teeth are arranged in a V-shape with no rearwards extension and there is a patch of teeth at each side of the palate, but there are no teeth on the tongue. The

Distribution and habitat

The blue and gold snapper is found in the eastern Pacific Ocean where it has a rather discontinuous distribution. It occurs at the mouth of the Gulf of California and southern Baja California, and along the western coast of Mexico, from southern Guatemala to Panama and Colombia. It also occurs at the Revillagigedo Islands of Mexico, Clipperton Island, Cocos Island of Costa Rica, Malpelo Island of Columbia and the Galápagos Islands in Ecuador. It is found where there are rocky substrates and coral reefs at depths down to at least .


Biology

The blue and gold snapper occasionally gathers in large daytime aggregations on rocky or coral reefs. In Panama's Gulf of Chriqui this species is restricted to areas where there are madreporite branching corals. At night this species forages for crabs, molluscs, cephalopods, shrimp, and small fish and they normally seek shelter during the day.


Fisheries

The blue and gold snapper is an important target species for subsistence fisheries, they catch it with hooks and lines. The catch is mostly sold as fresh fish.
