Adaptations of a moose include its antlers, digestive system and long legs. For instance, a bull moose grows antlers every year. The larger and more elaborate the antlers, the healthier the moose has to be to grow them, signifying to females that he is a worthy mate.
The complexity of the moose's digestive system is an example of environmental adaptation. A moose has to eat large amounts of vegetation to survive, so it chews and regurgitates its food several times to get as much nutritional value out of it as possible.
A moose is tall with long, strong legs, which help it to survive. For instance, a moose spends much of its time in the water hunting for nutritious aquatic plants, so its long legs are advantageous when walking through shallow water or swimming through deep water. Furthermore, it can run more than 30 miles per hour, a necessary adaptation in order to outrun predators. The moose's hooves and antlers are both adapted to fighting off those predators when outrunning them does not work, particularly when protecting its young.
The moose is native to cold northern environments, so it has adapted to low temperatures by growing thick, insulating fur to protect it from the cold.
