Bighorn sheep

Bighorn sheep

Bighorn sheep live in remote, treeless mountain terrains in western Canada, the western U.S., and northern Mexico. They have double-layered skulls shored with struts of bone for battle protection. They also have a broad, massive tendon linking skull and spine to help the head pivot and recoil from blows. Rams’ horns can weigh up to 30 pounds.

Check the Encyclopedia of Life’s entry on bighorn sheep.  There you can see a map of the species’ range, its taxonomic classification, images, videos, and a very detailed description with sections on physical description, ecology, molecular biology and genetics complete with genetic barcode, life history and behavior, conservation, and more.
