Fine Art Alaska Notecard 5 x 7 inches with a white envelope Sleeved in clear compostable plastic Made and printed in Alaska Photo by Plant Power The Alaska moose (Alces alces gigas) is the largest subspecies of moose. They are herbivores (plant eaters) and can consume up to 60 pounds a day! Females do not have antlers, but the bull moose grow new antlers each year during the spring and summer. Their giant, bony headgear is covered with velvet and nourished by a rich vascular network. The impressive racks can weigh up to 40 pounds. Once the antlers are fully grown in August, moose shed the velvet covering by rubbing the antlers against bushes and trees.
