Happy Rump Day!


What is that spot on Ambassador Wolf Atka's tail? The violet gland or supracaudal gland is an important gland located on the upper surface of a wolf's tail. It's believed to be used for intra-species signalling, scent marking, and perhaps to mark the entrances of wolf dens. It also makes a wolf's rump that much more interesting! Happy Rump Day!
