They are very fast. Wolves are the main predators of both fawns and adults. The moose is the largest extant species in the deer family.
Moose are distinguished by the palmate antlers of the males. The size and growth rate of antlers is determined by diet and age. Moose antlers are broad and flat with points along the outer edge. The antlers are spread greater than cm with the weight around 36 kg. After the mating season males drop their antlers to conserve energy for the winter. A new set of antlers will then regrow in the spring. Hagerty Ryan, U. The markhor is a large species of wild goat. It is also known as Shakhawat.

According to this idea, female horns or antlers should be found in species where competitive males are forced to hang around with each other more than in other species because they live in large herds that consist of "family" groups. This is, in fact, what is found in caribou and wildebeest, two of the prime example of antlered or horned females. The new theory, proposed by Ted Stankowich of the University of Massachusetts and Tim Caro of the University of California at Davis, is that females benefit from having horns or antlers if they are of a body size or live in a habitat that makes it hard for them to hide.
The more conspicuous the female, the more benefit they gain from horns or antlers, which would be needed for defense against predators. They may also benefit from competition with members of their own species for grazing spots. This would explain caribou and wildebeest nicely, as they both live in very open country, as well as a lot of other species.
