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.

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 1750 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.

Platypus are strictly protected by law and harsh penalties in Australia, which is agreeable with most, if not all, Australians, since the animals are not pests and are now national emblems. The Australian government and private groups like the Australian Platypus Conservancy keep close eyes on platypus populations and have proposed relocating some of the urban platypus to suitable natural areas where they have been driven from by development in the past.

Platypus are considered "common but vulnerable" by the government of Australia. It is plentiful in some areas, but is considered vulnerable due to habitat destruction from dams, irrigation projects, being caught in fish nets and lines, and water pollution.

The Australian Platypus Conservancy and the Melbourne Water Department together have surveyed and taken counts of the urban platypus populations. They found that platypus in the waterways were as healthy and well-fed as those in the wild, while some individual platypus from the waterways have migrated and re-colonized river banks with improved habitat.

Recently, platypus have started invading human-made urban waterways in Melbourne, Victoria, while disappearing from some wild areas, for reasons still not understood. The urban platypus most likely have been forced into artificial waterways due to destruction of their habitat by development, and there is enough live platypus food in the waterways to feed a platypus population.

Well-meaning people may try to rescue a platypus that is wandering and seems to be lost, a move that often proves harmful to people and platypus. A wild platypus captured by humans will probably die of shock. The rescuers may end up with days of pain and misery from a platypus sting. Wildlife education in Australia stresses leaving lost animals alone and calling a local office of the Australian Government Department of the Environment and Heritage.

Platypus were nearly wiped out by hunting, into the early twentieth century, for their fine, soft, waterproof fur. Nevertheless, humans, out of carelessness and ignorance, continue to make life miserable for the platypus. The animals become entangled in fishing hooks and lines, and in fishing nets; such encounters end in drowning or in the scarring of the bill. Tasmania platypuses are being impacted by infection from an introduced fungus and by chemical pollutants.

The platypus, almost as much as the kangaroo, has become a national symbol of Australia and of the odd, weird, and outright bizarre creatures native to that continent and country. The platypus is a symbol, as well, for the unique, the quirky, and the unexpected in nature, which makes the animal and its behavior a subject of curiosity and science education.

Predators of platypus, other than humans, include birds of prey such as hawks, eagles, and owls; Murray cod, a freshwater fish; and crocodiles. Carpet pythons, goanna lizards and rakali, or Australian water-rats, prey on young platypus in burrows. Carnivorous mammal species introduced by European settlers, including foxes, dogs, and cats, prey on platypus, although some of these predators are dealt painful ends by the poison spurs of male platypus.

The mother, having no nipples, nurses the young with milk that comes directly from her belly skin. In about four months, the young emerge for the first time from the burrow, each about a foot long and with a full coat of fur.

In the platypus, the combined abilities of electroreception and mechanoreception are so sensitive and detailed that they have become something like vision, providing a three-dimensional "view" of the platypus underwater world, and enabling the platypus to pinpoint, in all three dimensions, the exact locations of its prey.

In addition to detecting bursts of electricity from prey animals, the electroreceptors in a platypus bill can probably detect the tiny electric currents made by water flowing over and around rocks and sunken logs, thus producing a three-dimensional map of a river or lake bottom within the platypus brain.

These detect tiny, underwater bursts of electricity from the muscles of swimming creatures that the platypus hunts. The electroreceptors are intermingled with 60,000 mechanoreceptors, nerves ending at the skin in tiny "push rods" that respond to small pressure changes and detect the movements of prey animals underwater and on the bottoms of streams and ponds. Together, the two senses allow the platypus to home in on prey.

The monotremes, the echidnas and platypus, are the only living mammals that are known to have an ability to sense electricity. The platypus bill is something unique in nature, so sophisticated and advanced that no one can call the platypus "primitive." The skin surface of the bill contains 40,000 tiny electroreceptors, or specialized sensory nerve endings, arranged in rows along the length of the bill.

The mother incubates the eggs by holding them against her belly fur with her tail, maintaining a constant temperature of 90°F (31.5°C). The young hatch in about ten days, each tearing through the eggshell with a temporary egg tooth. The newly hatched, inch-long young are fragile and translucent, blind and furless, and at about the same stage of development as a newly born marsupial young.

Platypus are for the most part silent. Some naturalists have heard threatened platypus make soft, growling sounds that are only audible at close range. Lifespans for platypus in captivity and in the wild can reach sixteen years.

Individuals have been known to go into periods of torpor, or sluggishness and reduced activity with a lowering of body temperature, during the coldest months. Such a period, which can last up to six days, is not true hibernation but allows the animal to conserve energy in cold times.

Platypus blood is especially rich in red cells and hemoglobin, the substance in blood that carries oxygen. The platypus can also ration its blood oxygen supply by reducing its heartbeat from two hundred beats per minute to ten beats per minute.

When not out hunting, a platypus rests in its burrow for up to seventeen hours a day. Platypus are active throughout the year, even in cooler southern Australia and Tasmania, where water temperature drops nearly to the freezing point.
