The mustached walrus with its long tusks is most often found near the Arctic Circle, lying on the ice with hundreds of companions. These marine mammals are extremely social and sensitive. They typically use loud roars and snorts to communicate with each other but are truly aggressive during mating season. With wrinkled brown and pink hides, walruses are distinguished by their long white tusks, grizzly whiskers, flat flippers, and blubbery bodies. Dimensions: 13.2 x 8.7 x 5.4 centimeters.
