The White Shark: Introduction (介绍)
Many paleontologists are very interested in living groups, because the study of the living organisms can both unlock their evolutionary history and provide important keys towards interpreting their fossil record. Some living groups have ancient histories. For example, sharks have existed as a group for over 350 million years! Today, sharks and rays (elasmobranchs) are represented by over 600 species that show a remarkable range of ecological and morphological diversity. Unlike the true fishes, sharks do not have internal bone, but instead have a cartilaginous skeleton. Although many people are told that sharks are primitive in comparison to other groups, this is not true. Many sharks are efficient and specialized hunters that have thrived for millions of years.
This small exhibit shows an amazing predator: the great white shark (Carcharodon carcharias). The white shark is found in temperate waters throughout the world's oceans, and it is an important, though not common, predator in California's coastal habitats. Scientists from several organizations throughout California including the Point Reyes Bird Observatory, the Marine Mammal Center, the California Academy of Sciences, Bodega Bay Marine Laboratory, California Department of Fish and Game, and the Museum of Vertebrate Zoology at UC Berkeley, have been studying white sharks and their prey for several years in hopes to better understand their behavior and ecology.
Food and Feeding（觅食?) Behavior (行为)
White sharks are predatory animals that begin life by feeding on fish, rays, and other sharks, and as they grow, switch to feeding on marine mammals and scavenging on large animal carcasses. Their first mammalian prey are usually the small harbor seal, but as the sharks increase in size, they become large enough to eat sea lions, elephant seals, and small toothed whales. Attack strategy consists of a swift, surprise attack from below, inflicting a large, potentially fatal bite. The pinniped often dies from massive trauma or blood loss, but the bites may be superficial or misplaced on the body, allowing the seal to escape and survive the attacks with their scars as witness. Large white sharks will also scavenge on the carcasses of whale sharks, and on the fat-rich blubber layer of dead whales. They will occasionally feed on sea turtles and sea otters, and are known to attack, but not eat, humans.
Habitat(栖息地) and Distribution{;(生物的)分布区域}
The waters off central California offer a rich bounty of food for white sharks, and every summer and fall they actively feed in nearshore areas. The Farallon Islands, a national wildlife refuge about 27 miles off San Francisco, is a common feeding ground for the sharks. Four species of pinnipeds, the northern elephant seal, the California sea lion, the Steller sea lion, and the harbor seal, live around and breed on these islands, making a plentiful food resource for the white sharks. The coastal waters along central California, especially around the Año Nuevo State Reserve and along the Marin Headlands, is another common feeding area for the sharks. In the summer the sharks feed on seals and sea lions along the coast as far north as Oregon and occasionally the Gulf of Alaska, and in the Fall, they turn south and feed along the offshore islands. It is believed that female white sharks migrate to southern California to give live birth to their offspring. In abnormally warm-water (El Niño) years, white sharks are more plentiful off central California because both they, and their prey, are shifted north. The years 1984-84 and 1991-92 show high trends in white shark predatory activity, and were the warmest oceanic seasons in recent history.
