Lesser Grison
Galictis cuja · also called huron
Wearing a distinctive grey-and-black mask across its face, a lesser grison hunts small vertebrates across an enormous range of South American habitat, from open Patagonian grassland to forest edges further north.
Overview
The lesser grison, Galictis cuja, is a Least Concern mammal native to grassland, forest, and desert habitat across a broad range of South America, including Patagonia. Its distinctive masked facial pattern, its adaptability across dramatically different habitat types, and its agile hunting style make it one of the more visually striking and ecologically flexible mustelids found anywhere in South America.
A masked hunter with few habitat limits
While many mustelids specialise narrowly in a single type of terrain, the lesser grison instead moves comfortably between grassland, forest, and desert scrub, its agile hunting style and broad diet allowing it to thrive across an unusually wide range of South American environments.
Status
Least Concern, remaining widespread and generally stable across its broad range of habitat throughout South America.
