Desert bighorn sheep, male ram. The desert bighorn sheep occupies dry, rocky mountain ranges in the Mojave and Sonoran desert regions of California, Nevada and Mexico. The desert bighorn sheep is highly endangered in the United States, having a population of only about 4000 individuals, and is under survival pressure due to habitat loss, disease, over-hunting, competition with livestock, and human encroachment.
Species: Desert bighorn sheep, Ovis canadensis nelsoni

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.
Species: Mandelbrot fractal, Mandelbrot set

A Pacific harbor seal hauls out on a sandy beach. This group of harbor seals, which has formed a breeding colony at a small but popular beach near San Diego, is at the center of considerable controversy. While harbor seals are protected from harassment by the Marine Mammal Protection Act and other legislation, local interests would like to see the seals leave so that people can resume using the beach.

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

Kelp fronds and pneumatocysts. Pneumatocysts, gas-filled bladders, float the kelp plant off the ocean bottom toward the surface and sunlight, where the leaf-like blades and stipes of the kelp plant grow fastest. Giant kelp can grow up to 2' in a single day given optimal conditions. Epic submarine forests of kelp grow throughout California's Southern Channel Islands.
Species: Giant kelp, Macrocystis pyrifera
