Deer are mammals inhabiting diverse ecosystems globally. These herbivores are characterized by their specialized diets and, in most species, the presence of antlers on the males. The deer family, Cervidae, encompasses a remarkable range of sizes and forms, from small, elusive forest dwellers to towering, powerful creatures of northern woodlands.
The Uncontested Largest Deer
The largest extant species within the deer family is the moose, known scientifically as Alces alces. An adult moose can reach an average height of 1.4 to 2.1 meters (4 feet 7 inches to 6 feet 11 inches) at the shoulder, which is over 30 centimeters (1 foot) higher than the next largest deer, the wapiti or elk.
Male moose, often called bulls, weigh between 380 to 700 kilograms (838 to 1,543 pounds), with some large Alaskan moose exceeding 725 kilograms (1,600 pounds). Female moose, or cows, weigh from 200 to 490 kilograms (441 to 1,080 pounds). A distinguishing feature of the male moose is its impressive antlers, which can span more than 1.8 meters (6 feet) from tip to tip. Its size makes the moose a prominent presence in the northern forests of the Northern Hemisphere.
Distinctive Physical Characteristics
The moose’s physique is built for navigating its environment. Its long, powerful legs are adapted for moving through deep snow, marshy terrains, and dense forests. The front legs are notably longer than the hind legs, which aids in clearing obstacles like fallen trees.
A muscular hump over its shoulders supports the animal’s large head and heavy antlers. Male moose develop broad, palmate, or “hand-shaped,” antlers, unlike the pointed, twig-like antlers of many other deer species. These antlers are among the fastest-growing animal tissues, regenerating annually from spring to fall and shedding each winter.
Moose possess a dewlap, or “bell,” a flap of skin hanging from the throat, which may play a role in heat regulation or mating displays. Their specialized, prehensile upper lip is crucial for efficiently stripping leaves and twigs from woody vegetation.
Habitat and Lifestyle
Moose inhabit the boreal forests, taiga, and temperate broadleaf and mixed forests of the Northern Hemisphere. They favor areas near water sources like lakes, ponds, rivers, and swamps, which provide food and refuge. Their geographic distribution spans across North America, including most of Canada, Alaska, and northern regions of the contiguous United States, as well as Eurasia, encompassing Scandinavia, Russia, and parts of Eastern Europe and Asia.
As browsers, moose consume woody vegetation, including twigs, leaves, and bark from trees and shrubs. Aquatic vegetation forms a significant part of their diet, especially during warmer months.
Moose are solitary animals, particularly outside of the breeding season, or rut, though mothers and calves form strong bonds. Despite their large size, they are agile on land, capable of running up to 56 kilometers per hour (35 miles per hour), and are exceptional swimmers, able to swim for miles and dive underwater for aquatic plants.
