Elk eat a variety of foods depending on the season. Grasses, sedges, flowers and other soft plant foods compose their diet during summer months, while the growth of woody plants such as cedar and red maple make up their diet in winter. They also occasionally eat mushrooms.Know More
Elk are ruminants, which means that to digest their tough foods, they must regurgitate and chew it again after it is ingested. This process is sometimes referred to as chewing cud.
Elk have a particular fondness for dandelions, aster, hawkweed, violets and clover when grazing in summer. In winter, favored woody plants include wintergreen, eastern hemlock, sumac, jack pine, staghorn and basswood.
Elk have good hearing, smell and vision to help them avoid predators and find food. They are very noisy and social, and they use all their senses, including touch, to communicate with other members of their herd. Herds during summer can contain as many as 400 elk. Herds are matriarchal, led by a single female, although males organize the females into harems during the mating season. They generally feed only at early morning and late evening and spend the rest of their time either sleeping or chewing cud.
As herbivores, elk are important prey animals for many predators. However, their large size, formidable hooves, movement in herds, and, on males, antlers, mean that few predators attack adults.Learn more about Animal Reproduction
Polar bears reproduce via internal fertilization, with one male mating with several females during the mating season, staying with each for their three-day period of fertility. Mating occurs between late winter and early spring, after which gestation lasts anywhere between 195 and 265 days due to the females' ability to delay fetal development. Litter sizes range from one to four cubs but average two cubs per litter.Full Answer >
Camels reproduce by copulating during breeding season after the males compete for dominance. After a gestation period of 12 to 14 months, the female gives birth to a calf that weighs up to 80 pounds and that can stand and walk a short time after being born.Full Answer >
Jellyfish reproduction involves both sexual and asexual processes: the fertilization of eggs, the release of hatched larvae and the asexual cloning of these larvae to produce infant jellyfish. The life cycle of a jellyfish lasts only a few months, although the larval stage can lastÂ many years or decades.Full Answer >
Sea scallops reproduce through spawning. Some scallops have male and female reproductive capabilities, while others produce only eggs or sperm cells. During spawning, the scallops release large quantities of eggs and sperm into the water. Fertilized eggs quickly develop into tiny scallops that are suspended in the water like plankton. They soon develop hard shells and spend the rest of their lives on the ocean floor.Full Answer >
