Elk

-Elk cows(female) average 225 kilograms (500 lb), stand 1.3 metres (4.3 ft) at the shoulder, and are 2 metres (6.6 ft) from nose to tail.
-Only the males have antlers, which start growing in the spring and are shed each winter. The largest antlers may be 1.2 metres (3.9 ft) long and weigh 18 kilograms (40 lb)
-Elk share their habitat with the black bear
-Brainworm is a parasitic nematode that has been known to affect the spinal cord and brain tissue of elk, leading to death. The nematode has a carrier in the white-tailed deer in which it normally has no ill effects. Nonetheless, it is carried by snails, which can be inadvertently consumed by elk during grazing.This is an example of a parasitic relationship between the elk and the brainworm,because the elk is being harmed and the brainworm benfits.
-When approached by predators, the largest and most robust females may make a stand, using their front legs to kick at their attackers.During the fall, elk grow a thicker coat of hair, which helps to insulate them during the winter. Males, females and calves of Siberian and North American elk all grow thin neck manes
-Elk produce sexually,Female elk have a short estrus cycle of only a day or two, and matings usually involve a dozen or more attempts. By the autumn of their second year, females can produce one and, very rarely, two offspring, although reproduction is most common when cows weigh at least 200 kilograms (440 lb)
