Specially adapted for cold water, this shark’s tissues contain high levels of chemical compounds that act like anti-freeze and prevent ice crystals forming in the body. These sharks conserve energy by swimming very slowly—about 1.12 feet per second—but can exhibit short bursts of speed to ambush prey.

The largest fish in the Arctic Ocean—and the only shark found there year-round—the Greenland shark also inhabits the North Atlantic and Russian high Arctic. Infrequently observed at the surface, it can live in waters 7,200 feet deep and between 28.4 to 44.6 Fahrenheit (minus 2 to 7 degrees Celsius).

Measuring the Greenland shark’s growth rate is challenging because individuals are rarely recaptured. However, one shark tagged in 1936 had only grown 2.3 inches when it reappeared 16 years later.

scientists discovered Greenland sharks have a life expectancy of at least 272 years and could reach 392, give or take about 120 years. What’s more, these slow-growing creatures don’t reach reproductive age until around 150 years old.

Many shark species can be aged by counting growth bands on their vertebrae, like rings on a tree. The Greenland shark’s soft vertebrae do not have these bands, however. Instead, its age is determined by removing the layers of the lens of its eye—which continues growing throughout its lifetime—and radiocarbon dating the tissue in the center.

Despite its name, the Greenland shark is not only found in Greenland; it has been spotted as far away as the western Caribbean. Also known as the gray, ground, gurry, or sleeper shark, this animal lives in incredibly cold, deep waters, so it is much less studied than many of the more than 500 other shark species. It is one of the slowest sharks, too: Its scientific name, Somniosus microcephalus, roughly translates to “sleepy small-head.” Yet these rare animals may be a top predator.

The Greenland shark is the world’s longest living vertebrate. It can live for 400 years—twice the age of the longest-living land animal, the giant tortoise. There could be an individual in the ocean today that was alive during the 1665 Great Plague of London and George Washington’s presidential inauguration in 1789.

Like other deer (family Cervidae), moose have cloven hooves, and are therefore in the mammalian order Artiodactyla. Moose are the largest animals in the deer family, weighing as much as 1,750 lb (800 kg) and standing as tall as about 6.6 ft (2 m). The largest moose occur in Alaska (Alces alces gigas ).

The moose (Alces alces), also known as elk in Europe , is a horse-sized, northern species of deer that occurs in the boreal and north-temperate forests of both North America and Eurasia. At one time, the Eurasian and American moose were considered to be separate species, but these animals are fully interfertile and are now thought to be the same species. However, there are many geographically distinct subspecies of these animals.

If moose also occur in places where white-tailed deer are abundant, they may suffer from a debilitating nematode parasite known as brainworm (Parelaphostrongylus tenuis ). The deer population is resistant to this parasite, but the brainworm is abundant where the deer are common, and the moose population consequently suffers.

In some regions of eastern North America, white-tailed deer (Odocoileus virginianus ) have become quite abundant. This has largely happened because of human activities that create favorable habitat for the white-tailed deer, such as some types of forestry and the abandonment of agricultural lands.

Moose are hunted throughout their range, both for sport and as a source of wild meat and tough hides. Until rather recently, moose were overhunted throughout much of their range, and their populations were reduced to low levels. Now, however, the hunting of most moose populations is regulated, and their abundance is somewhat higher.

Moose diets are generally low in sodium, and these animals therefore crave salt. As a result, moose (and other deer) are sometimes seen along roadsides, eating vegetation that is relatively rich in sodium because of the use of road salt in winter.

The long legs of moose make it easy for them to feed relatively easily in the canopy of shrubs and trees. However, this trait, in combination with their short neck, makes it difficult for these animals to feed on lower-growing, herbaceous vegetation. Therefore, when grazing on grasses and forbs, moose often must kneel rather awkwardly.

During the summer, individual moose can be approached rather closely (and carefully) by canoe, and can be taken totally by wide-eyed surprise when they lift their heads above water again, subsequently running away with enormous splashes.

The upper lip of the moose is unusually large and prehensile, and is adapted to feeding on woody plants.

Moose feed on a wide variety of plants, and their diet varies seasonally. Most of the year moose feed by browsing on the young shoots and foliage of woody shrubs and short trees. During the summer these animals prefer to eat herbaceous vegetation, including aquatic plants, which they seek while standing in the water, often feeding beneath the surface.

Moose calves are born one or two at a time, and they are precocious, meaning they are capable of standing and moving about with their mother soon after birth. The calves nurse for up to a year, and moose can live for as many as 25 years. Moose are not very social animals, mostly coming together only for the purposes of breeding. In some regions with deep snow in the winter, moose may aggregate in dense stands of conifer trees, known as yards.

During the autumn rutting season, fights between evenly matched bull moose can be dramatic contests, and can lead to death for one of the combatants. Rarely, two bulls will lock their horns together so tightly that it causes the death of both animals. Bull moose are extremely aggressive during their rut, and at this time they are dangerous to humans.

While the antlers are growing they are covered with densely vascularized tissue known as velvet which dries once the antler growth is complete by the late summer. The dry velvet is removed by rubbing against trees and other solid objects leaving only the bare antler bone exposed. Male moose also have a large dewlap hanging under their neck sometimes called a bell.

The antlers of the oldest strongest males are especially large and wide (up to 6.6 ft [2m]) and they have intricate outgrowths known as tines on their edge which can number as many as forty. The antlers of moose are deciduous meaning they are grown during the springtime and summer for use in jousting with other males for access to females during the rutting season and are later shed in the late autumn or early winter.

Moose have large shovel-shaped antlers which are bony outgrowths of the frontal bones of their skull a characteristic shared with other species in the deer family. The antlers of moose only develop on male animals.

Moose are ruminants meaning their stomach is divided into four discrete chambers which are concerned with particular sequential aspects of digestion of the fibrous plantbiomass these animals feed upon. Moose ruminate meaning they regurgitate and rechew forage that has spent some time fermenting in one of the fore-chambers of the stomach.

Moose are unusual-looking animals with a long and large head long legs a short neck and tail and a hump over their shoulders which are taller than their hips. Moose convey a superficial appearance of ungainliness but they can run swiftly and skillfully over difficult uneven and wet terrain. Moose are also good swimmers.
