Image ID: 19680
Species: Moose, Alces alces
Location: Yellowstone National Park, Wyoming, USA | Roosevelt elk, adult bull male with large antlers. This bull elk has recently shed the velvet that covers its antlers. While an antler is growing, it is covered with highly vascular skin called velvet, which supplies oxygen and nutrients to the growing bone; once the antler has achieved its full size, the velvet is lost and the antler's bone dies. This dead bone structure is the mature antler, which is itself shed after each mating season. Roosevelt elk grow to 10' and 1300 lb, eating grasses, sedges and various berries, inhabiting the coastal rainforests of the Pacific Northwest.
