Sailing stone on the Death Valley Racetrack playa. The sliding rocks, or sailing stones, move across the mud flats of the Racetrack Playa, leaving trails behind in the mud. The explanation for their movement is not known with certainty, but many believe wind pushes the rocks over wet and perhaps icy mud in winter.

Four-eyed fish, found in the Amazon River delta of South America. The name four-eyed fish is actually a misnomer. It has only two eyes, but both are divided into aerial and aquatic parts. The two retinal regions of each eye, working in concert with two different curvatures of the eyeball above and below water to account for the difference in light refractivity for air and water, allow this amazing fish to see clearly above and below the water surface simultaneously.
Species: Four-eyed fish, Anableps anableps

Clipperton Rock, a 95' high volcanic remnant, is the highest point on Clipperton Island, a spectacular coral atoll in the eastern Pacific. The Pacific Ocean encircling the atoll is seen to the right of the white sand beach, and the lagoon inside the atoll is behind Clipperton Rock. By permit HC / 1485 / CAB (France).

Two Giant black sea bass hover in the kelp forest as a courting pair, part of a larger mating aggregation at Catalina Island. In summer months, giant black seabass gather in kelp forests in California to form mating aggregations leading to spawning. Courtship behaviors include circling of pairs of giant sea bass, production of booming sounds by presumed males, and nudging of females by males in what is though to be an effort to encourage spawning.
Species: Giant black sea bass, Stereolepis gigas

Blade Runner, the injured North Pacific humpback whale, is seen with her calf swimming alongside. This humpback whale showing extensive scarring, almost certainly from a boat propeller, on dorsal ridge. This female North Pacific humpback whale was first seen with the depicted lacerations near the island of Maui in the Hawaiian Islands in the mid-90s, and is the original humpback to bear the name 'Blade Runner'. This female has apparently recovered, as evidenced by her calf in the background. A South Pacific humpback whale endured a similar injury in Sydney Australia in 2001, and bears a remarkably similar scar pattern to the above-pictured whale.
Species: Humpback whale, Megaptera novaeangliae

The Kelp Forest offshore of La Jolla, California. A kelp forest. Giant kelp grows rapidly, up to 2' per day, from the rocky reef on the ocean bottom to which it is anchored, toward the ocean surface where it spreads to form a thick canopy. Myriad species of fishes, mammals and invertebrates form a rich community in the kelp forest. Lush forests of kelp are found throughout California's Southern Channel Islands.
Species: Giant kelp, Macrocystis pyrifera

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.
Species: Mandelbrot fractal, Mandelbrot set

Blue whale, exhaling in a huge blow as it swims at the surface between deep dives. The blue whale's blow is a combination of water spray from around its blowhole and condensation from its warm breath.
