The Arabian wolf is a subspecies of grey wolf that has adapted to live in impressively harsh conditions. This 40-pound wolf has a long coat in winter to insulate it against freezing temperatures, and while in summer it has a shorter coat, the longer fur remains along its back to help protect against the heat of the sun. It also has extra large ears to help disperse body heat. To escape the most miserable heat, it will dig deep dens and rest in the shade. To ensure it finds enough to eat, the Arabian wolf usually lives a solitary life except during breeding season or when food is readily found. Even then, they live only in pairs or small packs of 3-4 wolves. Its prey is anything from small birds, reptiles and hares to larger animals like gazelles and ibexes. But it cannot go entirely without water, so it sticks to gravel plains and the fringes of the desert.
