Ecuadorian squirrel monkey


The Ecuadorian squirrel monkey is a type of squirrel monkey. It had been considered a subspecies of the Guianan squirrel monkey, Saimiri sciureus, but was elevated to a full species, S. macrodon, based on a 2009 study by Carretero-Pinzón, et al. Based on subsequent genetic research by Jessica Lynch Alfaro, et al it was again reclassified as a subspecies of Humboldt's squirrel monkey.
The Ecuadorian squirrel monkey lives in the western Brazilian Amazon, as well as southern Colombia, eastern Ecuador and northern and eastern Peru. It lives in humid tropical and subtropical forest, preferring dense forest but able to live in secondary forest and disturbed forest as well. It can live at elevations up to, but where it has been studied in Ecuador it prefers elevations under.
The Ecuadorian squirrel monkey has a head and body length of between with a tail length between. Males weigh between and females weigh between. Its coloration is similar to that of the Guianan squirrel monkey but its fur is darker.
