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.
Species: Great white shark, Carcharodon carcharias
Location: Guadalupe Island (Isla Guadalupe), Baja California, Mexico

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 shows scarring on the left side of its body, almost certainly the result of bites from another white shark. Certain formidable prey, such as huge elephant seals who have claws and large jaws, can also inflict injuries on the shark during the course of an attack. Such injuries, especially to the eyes or gills, could be fatal to the shark. In this case the shark has survived its injuries and the resulting scars are helping researchers identify this shark.

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.
