Milky Way during Full Lunar Eclipse over Arch Rock, Joshua Tree National Park, April 4 2015. The arch and surrounding landscape are illuminated by the faint light of the fully-eclipsed blood red moon. Light from the sun has passed obliquely through the Earth's thin atmosphere, taking on a red color, and is then reflected off the moon and reaches the Earth again to light the arch. The intensity of this light is so faint that the Milky Way can be seen clearly at the same time.

The leafy seadragon (Phycodurus eques) is found on the southern and western coasts of Australia. Its extravagent appendages serve only for camoflage, since it has a nearly-invisible dorsal fin that propels it slowly through the water. The leafy sea dragon is the marine emblem of South Australia.

Pyrosome drifting through a kelp forest, Catalina Island. Pyrosomes are free-floating colonial tunicates that usually live in the upper layers of the open ocean in warm seas. Pyrosomes are cylindrical or cone-shaped colonies made up of hundreds to thousands of individuals, known as zooids.

Roosevelt elk, adult bull male with large antlers. This bull elk has recently shed the velvet that covers its antlers. While an antler is growing, it is covered with highly vascular skin called velvet, which supplies oxygen and nutrients to the growing bone; once the antler has achieved its full size, the velvet is lost and the antler's bone dies. This dead bone structure is the mature antler, which is itself shed after each mating season. Roosevelt elk grow to 10' and 1300 lb, eating grasses, sedges and various berries, inhabiting the coastal rainforests of the Pacific Northwest.
Species: Roosevelt elk, Cervus canadensis roosevelti

Radio telescope antenna, part of the Very Long Baseline Array (VLBA). The Very Long Baseline Array (VLBA) is a system of ten radio telescopes which are operated remotely from their Array Operations Center located in Socorro, New Mexico, as a part of the National Radio Astronomy Observatory (NRAO). These ten radio antennas work together as an array that forms the longest system in the world that uses very long baseline interferometry.

Courting pair of southern right whales underwater, Eubalaena australis. In this image, the male is below and inverted (belly up) and the female is at the surface. While the posture in this photo isn't quite mating, it is a courting behavior that often precedes mating.

Huge California Sea Lion Male Underwater, a bull, patrolling his breeding harem and territory, Coronado Islands, Mexico. His sagittal crest, the bony bump on his head that distinguishes adult male sea lions, is clearly seen. This particular sea lion bears an orange tag on his left foreflipper, probably as a result of rescue and release as a young sea lion years earlier.

Red gorgonian on rocky reef, below kelp forest, underwater. The red gorgonian is a filter-feeding temperate colonial species that lives on the rocky bottom at depths between 50 to 200 feet deep. Gorgonians are oriented at right angles to prevailing water currents to capture plankton drifting by.

Eureka Dunes. The Eureka Valley Sand Dunes are California's tallest sand dunes, and one of the tallest in the United States. Rising 680' above the floor of the Eureka Valley, the Eureka sand dunes are home to several endangered species, as well as "singing sand" that makes strange sounds when it shifts. Located in the remote northern portion of Death Valley National Park, the Eureka Dunes see very few visitors.

Sky Rock at night, light by moonlight with stars in the clear night sky above. Sky Rock petroglyphs near Bishop, California. Hidden atop an enormous boulder in the Volcanic Tablelands lies Sky Rock, a set of petroglyphs that face the sky. These superb examples of native American petroglyph artwork are thought to be Paiute in origin, but little is known about them.

Aerial photo of the San Rafael Reef at dawn. A fold in the Earth's crust leads to this inclined section of the San Rafael Reef, at the eastern edge of the San Rafael Swell. Clearly seen are the characteristic triangular flatiron erosion patterns that typical this formation. The colors seen here arise primarily from Navajo and Wingate sandstone.

California Brown Pelican claps its jaws, sometimes rapidly several times, perhaps to dislodge debris or simply because its fun and feels good. This is not the same as the "yawn" that precedes a head throw. Adult winter non-breeding plumage. Mandible clap, jaw clap.

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.

Male elephant seals (bulls) rear up on their foreflippers and fight in the surf for access for mating females that are in estrous. Such fighting among elephant seals can take place on the beach or in the water. They bite and tear at each other on the neck and shoulders, drawing blood and creating scars on the tough hides.
Species: Elephant seal, Mirounga angustirostris
