An important structural adaptation of the moose is the two large toes it has on its hooves. These two toes are spread apart which allows the moose's weight to be more evenly distributed and better balanced. This allows the moose to walk on deep layers of snow without sinking into the snow.

It is likely that the moose developed this adaptation because of the cold climates favoured by the moose. Moose are forced to travel around in deep snow during the winter to find food, shelter and to escape from predators. The moose’s two large toes enable it to move around easier in snow as they would not become bogged down in deep snow. This adaptation also ensures that moose are able to run away from lighter predators like wolves who do not have as much of a problem with sinking into deep snow, giving them a higher chance of survival.
