They have enormous antlers

Male moose, called bulls, start to grow antlers during spring. These distinctive broad palmate antlers can span up to 6 feet in width and weigh as much as 40 pounds. Palmate antlers have a flat, palm-like structure with tines or points, which is uncommon for other deer family members with twig-like structured antlers.  

Interestingly, only bulls grow antlers, each with a unique pattern. All male moose grow and lose their antlers. Moose shed their antlers between mid-November and March.

Furthermore, the shed antlers play a crucial role in the ecosystem. Smaller mammals like squirrels, mice, and porcupines rely on fallen moose antlers to extract vital nutrients for bone strength, health, and reproduction. 

Birds, including woodpeckers and grouse, also benefit from consuming the antler fragments. Meanwhile, decomposition enriches the soil, fostering plant growth and supporting a more sustainable ecosystem.
