White southern right whale calf underwater, Eubalaena australis. About five per cent of southern right whales are born white due to a condition known as grey morphism and will gradually turn dark as they age. They are not albino (which is a complete lack of pigmentation). Sometimes referred to as "brindled", the white coloration is a recessive genetic trait and only lasts a few months. Typically, but not always, white calves will become much darker as they mature but will still be somewhat lighter than normal even as adults, Eubalaena australis, Puerto Piramides, Chubut, Argentina

The bisons massive head is its most characteristic feature. Its forehead bulges because of its convex-shaped frontal bone. Its shoulder hump, dwindling bowlike to the haunches, is supported by unusually long spinal vertebrae. Over powerful neck and shoulder muscles grows a great shaggy coat of curly brown fur, and over the head, like an immense hood, grows a shock of black hair. Its forequarters are higher and much heavier than its haunches. A mature bull stands about 6 1/2 feet (2 meters) at the shoulder and weighs more than 2,000 pounds (900 kilograms). The bisons horns are short and black. In the male they are thick at the base and taper abruptly to sharp points as they curve outward and upward; the females horns are more slender, Bison bison, Yellowstone National Park, Wyoming

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, Cervus canadensis roosevelti, Redwood National Park, California
