Mono Aullador.
Howler monkeys (genus Alouatta monotypic in subfamily Alouattinae) are among the largest of the New World monkeys. Fifteen species are currently recognised. Previously classified in the family Cebidae, they are now placed in the family Atelidae. These monkeys are native to South and Central American forests. Threats to howler monkeys include human predation, habitat destruction and being captured for captivity as pets or zoo animals.The Holacanthus passer or Royal Angel zone includes the central Gulf of California, Guadalupe Island and the southern coast of Ecuador. They commonly inhabit near coral and rock reefs at depths from 3 m to at least 80 m. Juveniles can be found in shallower waters.
