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.

Fractal design. Fractals are complex geometric shapes that exhibit repeating patterns typified by self-similarity, or the tendency for the details of a shape to appear similar to the shape itself. Often these shapes resemble patterns occurring naturally in the physical world, such as spiraling leaves, seemingly random coastlines, erosion and liquid waves. Fractals are generated through surprisingly simple underlying mathematical expressions, producing subtle and surprising patterns. The basic iterative expression for the Mandelbrot set is z = z-squared + c, operating in the complex (real, imaginary) number set.
Species: Mandelbrot fractal, Mandelbrot set

King penguins at Salisbury Plain, Bay of Isles, South Georgia Island. Hundreds of thousands of pairs of king penguins nest here, laying eggs in December and February, then alternating roles between foraging for food and caring for the egg or chick.

Wandering albatross, on nest and the Prion Island colony. The wandering albatross has the largest wingspan of any living bird, with the wingspan between, up to 12' from wingtip to wingtip. It can soar on the open ocean for hours at a time, riding the updrafts from individual swells, with a glide ratio of 22 units of distance for every unit of drop. The wandering albatross can live up to 23 years. They hunt at night on the open ocean for cephalopods, small fish, and crustaceans. The survival of the species is at risk due to mortality from long-line fishing gear.
Species: Wandering albatross, Diomedea exulans

Humpback whale lunge feeding on Antarctic krill, with mouth open and baleen visible. The humbpack's pink throat grooves are seen as its pleated throat becomes fully distended as the whale fills its mouth with krill and water. The water will be pushed out, while the baleen strains and retains the small krill.
Species: Humpback whale, Megaptera novaeangliae
Location: Gerlache Strait, Antarctic Peninsula, Antarctica

The Second Wave at Sunset, North Coyote Buttes. The Second Wave, a curiously-shaped sandstone swirl, takes on rich warm tones and dramatic shadowed textures at sunset. Set in the North Coyote Buttes of Arizona and Utah, the Second Wave is characterized by striations revealing layers of sedimentary deposits, a visible historical record depicting eons of submarine geology.
