Photo of 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. :: Image #13120

Photo of A great white shark swims toward the photographer. Perhaps the shark is considering him as possible prey? The photographer, a "shark diver" is safely situated in a sturdy metal cage. The best location in the world to "shark dive" to view great white sharks is Mexico's Guadalupe Island. :: Image #19469
Photo of A great white shark is countershaded, with a dark gray dorsal color and light gray to white underside, making it more difficult for the shark's prey to see it as approaches from above or below in the water column. The particular undulations of the countershading line along its side, where gray meets white, is unique to each shark and helps researchers to identify individual sharks in capture-recapture studies. Guadalupe Island is host to a relatively large population of great white sharks who, through a history of video and photographs showing their countershading lines, are the subject of an ongoing study of shark behaviour, migration and population size. :: Image #19467

Photo of Sea lion head profile, showing small external ear, prominant forehead typical of adult males, whiskers. This sea lion is hauled out on public docks in Astoria's East Mooring Basin. This bachelor colony of adult males takes up residence for several weeks in late summer on public docks in Astoria after having fed upon migrating salmon in the Columbia River. The sea lions can damage or even sink docks and some critics feel that they cost the city money in the form of lost dock fees. :: Image #19420
Photo of A bull sea lion shows a brand burned into its hide by the Oregon Department of Fish and Wildlife, to monitor it from season to season as it travels between California, Oregon and Washington. Some California sea lions, such as this one C-704, prey upon migrating salmon that gather in the downstream waters and fish ladders of Bonneville Dam on the Columbia River. The "C" in its brand denotes Columbia River. These sea lions also form bachelor colonies that haul out on public docks in Astoria's East Mooring Basin and elsewhere, where they can damage or even sink docks. :: Image #19419

Photo of The Mandelbrot Fractal. 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. :: Image #18739

More than 30,000 elk from 8 different herds summer in Yellowstone and approximately 15,000 to 22,000 winter in the park. Bulls grow antlers annually from the time they are nearly one year old. When mature, a bulls rack may have 6 to 8 points or tines on each side and weigh more than 30 pounds. The antlers are shed in March or April and begin regrowing in May, when the bony growth is nourished by blood vessels and covered by furry-looking velvet. :: Image #13154

Photo of Desert agave, also known as the Century Plant, blooms in spring in Anza-Borrego Desert State Park. Desert agave is the only agave species to be found on the rocky slopes and flats bordering the Coachella Valley. It occurs over a wide range of elevations from 500 to over 4,000. It is called century plant in reference to the amount of time it takes it to bloom. This can be anywhere from 5 to 20 years. They send up towering flower stalks that can approach 15 feet in height. Sending up this tremendous display attracts a variety of pollinators including bats, hummingbirds, bees, moths and other insects and nectar-eating birds. :: Image #11551

Photo of Detail within the Mandelbrot set fractal. This detail is found by zooming in on the overall Mandelbrot set image, finding edges and buds with interesting features. 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. :: Image #10395

Photo of Cardon cactus, near La Paz, Baja California, Mexico. Known as the elephant cactus or Mexican giant cactus, cardon is largest cactus in the world and is endemic to the deserts of the Baja California peninsula. Some specimens of cardon have been measured over 21m (70) high. These slow-growing plants live up to 300 years and can weigh 25 tons. Cardon is often mistaken for the superficially similar saguaro of Arizona and Sonora, but the saguaro does not occupy Baja California. :: Image #5498

Photo of SIO Pier. The Scripps Institution of Oceanography research pier is 1090 feet long and was built of reinforced concrete in 1988, replacing the original wooden pier built in 1915. The Scripps Pier is home to a variety of sensing equipment above and below water that collects various oceanographic data. The Scripps research diving facility is located at the foot of the pier. Fresh seawater is pumped from the pier to the many tanks and facilities of SIO, including the Birch Aquarium. The Scripps Pier is named in honor of Ellen Browning Scripps, the most significant donor and benefactor of the Institution. :: Image #22293

Photo of Sea otters mating. The male holds the female's head or nose with his jaws during copulation. Visible scars are often present on females from this behavior. Sea otters have a polygynous mating system. Many males actively defend territories and will mate with females that inhabit their territory or seek out females in estrus if no territory is established. Males and females typically bond for the duration of estrus, or about 3 days. :: Image #21606

Photo of Large male elk (bull) in snow covered meadow near Madison River. Only male elk have antlers, which start growing in the spring and are shed each winter. The largest antlers may be 4 feet long and weigh up to 40 pounds. Antlers are made of bone which can grow up to one inch per day. While growing, the antlers are covered with and protected by a soft layer of highly vascularised skin known as velvet. The velvet is shed in the summer when the antlers have fully developed. Bull elk may have six or more tines on each antler, however the number of tines has little to do with the age or maturity of a particular animal. :: Image #19692

Photo of The Botanical Building in Balboa Park, San Diego. The Botanical Building, at 250 feet long by 75 feet wide and 60 feet tall, was the largest wood lath structure in the world when it was built in 1915 for the Panama-California Exposition. The Botanical Building, located on the Prado, west of the Museum of Art, contains about 2,100 permanent tropical plants along with changing seasonal flowers. The Lily Pond, just south of the Botanical Building, is an eloquent example of the use of reflecting pools to enhance architecture. The 193 by 43 foot pond and smaller companion pool were originally referred to as Las Lagunas de las Flores (The Lakes of the Flowers) and were designed as aquatic gardens. The pools contain exotic water lilies and lotus which bloom spring through fall. :: Image #23096

Photo of 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. :: Image #22575
