Species overview
About the Greater Grison
The greater grison has a long low body, short legs and a striking pale stripe separating its dark face and underside from its grizzled back. It belongs to the same mammal family as weasels and otters. It hunts small animals and uses a variety of habitats, often near water. An animal moving quickly through vegetation may offer only a short glimpse, so note its outline as well as its colors. Looking carefully at less familiar mammals can reveal how many different hunters share Costa Rica's landscapes.
Explorer activity: Sketch a grison beside a river otter. Compare the head, legs and tail without relying only on color.
Your discovery notes: Record the date, place and habitat. Add a sketch or a photograph taken from a distance. Write what you observed and one question you would like to investigate. If the species is uncertain, keep that uncertainty in your notes.
