The plural form of moose is moose. The pronunciation and spelling do not change. A group of moose is called a herd of moose.
Moose are the largest of all of the deer species, weighing up to 1,800 pounds. The average lifespan for a moose in the wild is 15 to 20 years. Moose can run up to 35 miles per hour, and calves can outrun a human being only five days after birth. Male moose have antlers that reach up to six feet in width. Their antlers fall off before winter and grow back in the spring. The males and females only come together to mate, ignoring each other the rest of the year.
