Ecuadorian squirrel monkey explained

The Ecuadorian squirrel monkey (Saimiri cassiquiarensis macrodon) 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.^[1] Based on subsequent genetic research by Jessica Lynch Alfaro, et al it was again reclassified as a subspecies of Humboldt's squirrel monkey.^{[2] [3] [4]}

The Ecuadorian squirrel monkey lives in the western Brazilian Amazon, as well as southern Colombia, eastern Ecuador and northern and eastern Peru.^[5] It lives in humid tropical and subtropical forest, preferring dense forest but able to live in secondary forest and disturbed forest as well.^[5] It can live at elevations up to 1200lk=onNaNlk=on, but where it has been studied in Ecuador it prefers elevations under 500m (1,600feet).^[5]

The Ecuadorian squirrel monkey has a head and body length of between 25and with a tail length between 34and.^[5] Males weigh between 885and and females weigh between 590and.^[5] Its coloration is similar to that of the Guianan squirrel monkey but its fur is darker.^[5]
