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 ...
The first scientific descriptions of the animal's remains were made by Irish physician Thomas Molyneux in 1695, who identified large antlers from Dardistown—which were apparently commonly unearthed in Ireland—as belonging to the elk (known as the moose in North America), concluding that it was once abundant on the island.

Male elk have large, blood- and nerve-filled antlers, which they routinely shed each year as weather warms-up. Males also engage in ritualized mating behaviors during the mating season , including posturing to attract females, antler-wrestling (sparring), and bugling , a loud series of throaty whistles, bellows, screams, and other vocalizations ...
Male antlers can grow to lengths of fifty-one inches, while female antlers are smaller, at twenty inches. ... and a herd of muskoxen share the same territory at Alaska’s Large Animal Research ...
The other major difference is that antlers undergo an annual cycle of shedding and growth, whereas horns are normally kept for the animal’s entire lifespan (though the pronghorn is an exception ...
The antlers establish social rank and affect mating success. [6] Female Alaska moose stand on average 1.8 m (5.9 ft) at the shoulder and can weigh close to 478 kg (1,054 lb). [ 1 ] The largest Alaska moose was shot in western Yukon in September 1897; it weighed 820 kg (1,808 lb), and was 2.33 m (7.6 ft) tall at the shoulder. [ 7 ]
Antlers are made of bone and covered with “velvet”—a thin, soft layer of skin and blood vessels that gets scraped off the antler over time. Later in the year, those antlers are shed, making ...
Antlers are considered one of the most exaggerated cases of male secondary sexual traits in the animal kingdom, [63] and grow faster than any other mammal bone. [64] Growth occurs at the tip, initially as cartilage that is then mineralized to become bone. Once the antler has achieved its full size, the velvet is lost and the antler's bone dies.
