In moose, antlers may act as large hearing aids. Equipped with large, highly adjustable external ears, moose have highly sensitive hearing. Moose with antlers have more sensitive hearing than moose without, and a study of trophy antlers with an artificial ear confirmed that the large flattened (palmate) antler behaves like a parabolic reflector ...
In the largest subspecies, the antlers of large bulls can range up to 100 cm (39 in) in width and 135 cm (53 in) in beam length. They have the largest antlers relative to body size among living deer species. [116] Antler size measured in number of points reflects the nutritional status of the reindeer and climate variation of its environment.
The growth of antlers among the females of the deer species is only normal in female reindeer. 4. A Reindeer Grows New Antlers Every Year . Reindeer grow new antlers yearly.
This dead bone structure is the mature antler. In most cases, the bone at the base is destroyed by osteoclasts and the antlers eventually fall off. [62] As a result of their fast growth rate antlers place a substantial nutritional demand on deer; they thus can constitute an honest signal of metabolic efficiency and food gathering capability. [65]
The antlers are considerably larger than those of living moose, being on average over twice the volume of moose antlers. [30] For body size, at about 450–600 kg (990–1,320 lb) and up to 700 kg (1,540 lb) or more, [34] [33] [35] the Irish elk was the heaviest known cervine ("Old World deer"); [5] and tied with the extant Alaska moose (Alces ...
The giant anteater can be identified by its large size, long, narrow muzzle, and long bushy tail. [14] It has a total body length of 182 to 217 cm (72 to 85 in). Males weigh 33 to 50 kg (73 to 110 lb) and females weigh 27 to 47 kg (60 to 104 lb), [ 6 ] [ 15 ] [ 16 ] making the giant anteater the biggest extant species in its suborder.
The term "horn" is also popularly applied to other hard and pointed features attached to the head of animals in various other families: Giraffidae: Giraffes have one or more pairs of bony bumps on their heads, called ossicones. These are covered with furred skin. Cervidae: Most deer have antlers, which are not
The hair feels coarse, more like that of a deer than the glossy hair typical of antelopes. [26] The fetlocks are marked with white patches. [26] One pair of horns is located between the ears, and the other on the forehead. The posterior horns are always longer than the anterior horns, which might be mere fur-covered studs. While the posterior ...
