Moose vs. Caribou: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on January 17, 2024
Moose are large, solitary animals with broad, palmate antlers, primarily found in North America and Europe, whereas caribou, also known as reindeer, are smaller, herd-dwelling animals with branching antlers, found in arctic and subarctic regions.

Key Differences

Moose are the largest members of the deer family, known for their massive size and distinctive, broad antlers. Caribou, on the other hand, are smaller and renowned for their long migrations and unique antlers that both males and females possess.
Moose are typically solitary animals, preferring to live alone or in small family groups. Caribou are social creatures, known for forming large herds, especially during migration seasons. This difference in social behavior marks a significant distinction between the two species.
In terms of habitat, moose are commonly found in the forests of North America and Northern Europe, where they browse on leaves and aquatic vegetation. Caribou are adapted to colder, tundra environments of the Arctic and subarctic, feeding on lichens and other tundra vegetation.
The antlers of a moose are palmate, meaning they are broad and flat, resembling an open hand. In contrast, caribou have branching, beam-like antlers. This difference in antler shape and structure is one of the most visually distinguishable features between the two species.
Reproductive behaviors also differ. Moose have a more solitary mating system, with males competing for females during the rut. Caribou, however, exhibit less intense mating competitions, with males gathering small groups of females during the breeding season.
