Scent (Ex): A caribou can detect opponents within 30 feet. The exact location is not revealed unless the creature is within 5 feet.

Carrying Capacity: A light load for a caribou is up to 75 pounds; a medium load, 76-150 pounds; and a heavy load, 151-225 pounds. A caribou can drag 1,125 pounds.

Caribou usually flee from predators or threats. However, if cornered they can attack with a powerful butt of their antlers. Caribou can be trained to serve as pack beasts or drag loads, such as sledges.
