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.

A California brown pelican entangled in a plastic bag which is wrapped around its neck. This unfortunate pelican probably became entangled in the bag by mistaking the floating plastic for food and diving on it, spearing it in such a way that the bag has lodged around the pelican's neck. Plastic bags kill and injure untold numbers of marine animals each year.

Giant black sea bass in the kelp forest at Catalina Island. An Endangered Giant Sea Bass can reach up to 8 feet in length and 500 pounds, seen here amid the giant kelp forest of Catalina Island. Once nearly fished to extinction and now thought to be at risk of a genetic bottleneck, the giant sea bass is slowly recovering and can be seen in summer months in California's kelp forests.
