A great white shark bearing a white plastic researcher's identification ID tag near its dorsal fin swims through the clear waters of Isla Guadalupe, far offshore of the Pacific Coast of Baja California. Guadalupe Island is host to a concentration of large great white sharks, which visit the island to feed on pinnipeds and tuna.

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.
Species: Sea otter, Enhydra lutris

Torrey Pines balloon aerial survey photo. Torrey Pines seacliffs, rising up to 300 feet above the ocean, stretch from Del Mar to La Jolla. On the mesa atop the bluffs are found Torrey pine trees, one of the rare species of pines in the world. Peregine falcons nest at the edge of the cliffs. This photo was made as part of an experimental balloon aerial photographic survey flight over Torrey Pines State Reserve, by permission of Torrey Pines State Reserve.

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.

A great white shark swims through the clear waters of Isla Guadalupe, far offshore of the Pacific Coast of Mexico's Baja California. Guadalupe Island is host to a concentration of large great white sharks, which visit the island to feed on pinnipeds and use it as a staging area before journeying farther into the Pacific ocean.
