By Ryan Fehlig
Kingdom: Animalia
Phylum: Chordata
Subphylum: Vertebrata
Class: Chondrichthyes
Order: Lamniformes
Family: Lamnidae
Genus: Carcharodon
Species: Carcharodon carcharias
Geographic Range

The white shark is widely distributed throughout temperate and subtropical regions of the world's oceans.

Biogeographic Regions: oceanic islands (native ); indian ocean (native ); atlantic ocean (native ); pacific ocean (native ).
Habitat

Occurs in coastal and offshore waters of continental shelves where the sea surface temperatures range between 12 and 24 degrees Celsius; may come close to shore and enter small bays and harbors; may also occur off distant oceanic islands. It occurs from surface waters to depths of 1280 m.

Aquatic Biomes: benthic ; reef ; coastal .
Reproduction

Very little is known of reproduction in the white shark; only recently has a pregnant female been examined. It is presumed to be ovoviparious, and that the young gorge on fertilized eggs within the brood chamber (but direct evidence is lacking). Reproductive seasonality is unknown, although spring-summer parturition is suggested. Litter size was previously only thought to be about two young, but new evidence suggests as many as 9 to 11. Birth has never been observed, but live birth is assumed.
Behavior

Behavioral data has been difficult to obtain and interpret, but the conventional theory that white sharks only swim, eat, and make little sharks still appears to be true. Regardless of their size, white sharks occur singly or as scattered, unassociated individuals over several square kilometers. Aggregation of sharks may occur around a large or concentrated food source, creating the possibility of a feeding frenzy. They display a high degree of sexual segregation geographically, though this pattern fluctuates for unknown reasons; size segregation is also believed to be a characteristic of white sharks. Seasonal distribution, occurring primarily in the nothern latitudes, is correlated with the seasonal availability of prey and sea surface temperatures. Tagged individuals have demonstrated vertical movements through water temperatures from 17.8 degrees C and 5 degrees C during its daily swimming activities.

Key behaviors: natatorial ; motile .
Food Habits

A voracious and efficient predator. Its prey includes a wide variey of bony fishes, including salmon, hake, halibut, mackeral, and tunas; other sharks; sea turtles; seabirds; and marine mammals, such as seals, sea lions, sea otters, and porpoises. Traditionally, white sharks were thought to be driven into a frenzy by the scent of blood. Recent research, however, shows that the white shark is a methodical feeder, employing extremely sophisticated food-finding mechanisms. It has a well-developed sense of smell, better eyesight than previously thought, a pattern of cells on the underside of its snout that enable it to respond to changes in water pressure, and an electrical sense that is unrivaled. Many experts believe that these sharks attack slow-moving prey, such as juveniles or those which are injured, by coming up on them from behind or below, taking one bite, and then waiting for the animal to weaken from the loss of blood before moving in for the kill.
Economic Importance for Humans: Negative

None known, other than keeping tourists away from certain beaches and feeding on an occasional swimmer.
Economic Importance for Humans: Positive

There is a considerable market for the jaws with the teeth intact. In addition, the flesh and fins may be used for food, the liver for oil, the skin for leather, and the carcass for fish meal. It is also a popular game fish, as well as the subject of some very lucrative movies.
Conservation Status

The world population is unknown, as is any indication on whether total white shark numbers are increasing or decreasing. Many experts believe that the population of white sharks in South Australia has undergone a serious decline in recent years, but there are insufficient data to adequately estimate the the species' population size or to assess human impact on it. In 1989, the Threatened Fishes Subcommittee of the Australian Society for Fish Biology added the white shark to the Australian Threatened Fishes List in the "uncertain status" category.
Other Comments

Despite the world-wide attention given to the white shark through documentaries and articles, it remains one of the most poorly understood of the world's sharks. Unfortunately, the general population believes the white shark to be a mindless, random killers - man-eaters - largely because of movies like "Jaws" and other horror stories, and would feel safer if the species were eradicated. Exactly why sharks attack humans is unknown - possibly raw aggression, territoriality, or misidentification (i.e. the sillhoette of a person lying on a surfboard strongly resembles that of a seal or sea lion from below). What is known is that white sharks do not attack humans out of hunger; in other words, they do not attack people to eat them. Most attacks, even those that prove fatal, do not result in any consumption of the victim - whole or in part. If death occurs, it is likely to be the result of loss of blood, loss of tissue, or shock.

Phylum: Chordata
Subphylum: Vertebrata
Class: Chondrichthyes
Order: Lamniformes
Family: Lamnidae
Genus: Carcharodon
Species: Carcharodon carcharias
Geographic Range

The white shark is widely distributed throughout temperate and subtropical regions of the world's oceans.

Biogeographic Regions: oceanic islands (native ); indian ocean (native ); atlantic ocean (native ); pacific ocean (native ).
Habitat

Occurs in coastal and offshore waters of continental shelves where the sea surface temperatures range between 12 and 24 degrees Celsius; may come close to shore and enter small bays and harbors; may also occur off distant oceanic islands. It occurs from surface waters to depths of 1280 m.

Aquatic Biomes: benthic ; reef ; coastal .
Reproduction

Very little is known of reproduction in the white shark; only recently has a pregnant female been examined. It is presumed to be ovoviparious, and that the young gorge on fertilized eggs within the brood chamber (but direct evidence is lacking). Reproductive seasonality is unknown, although spring-summer parturition is suggested. Litter size was previously only thought to be about two young, but new evidence suggests as many as 9 to 11. Birth has never been observed, but live birth is assumed.
Behavior

Behavioral data has been difficult to obtain and interpret, but the conventional theory that white sharks only swim, eat, and make little sharks still appears to be true. Regardless of their size, white sharks occur singly or as scattered, unassociated individuals over several square kilometers. Aggregation of sharks may occur around a large or concentrated food source, creating the possibility of a feeding frenzy. They display a high degree of sexual segregation geographically, though this pattern fluctuates for unknown reasons; size segregation is also believed to be a characteristic of white sharks. Seasonal distribution, occurring primarily in the nothern latitudes, is correlated with the seasonal availability of prey and sea surface temperatures. Tagged individuals have demonstrated vertical movements through water temperatures from 17.8 degrees C and 5 degrees C during its daily swimming activities.

Key behaviors: natatorial ; motile .
Food Habits

A voracious and efficient predator. Its prey includes a wide variey of bony fishes, including salmon, hake, halibut, mackeral, and tunas; other sharks; sea turtles; seabirds; and marine mammals, such as seals, sea lions, sea otters, and porpoises. Traditionally, white sharks were thought to be driven into a frenzy by the scent of blood. Recent research, however, shows that the white shark is a methodical feeder, employing extremely sophisticated food-finding mechanisms. It has a well-developed sense of smell, better eyesight than previously thought, a pattern of cells on the underside of its snout that enable it to respond to changes in water pressure, and an electrical sense that is unrivaled. Many experts believe that these sharks attack slow-moving prey, such as juveniles or those which are injured, by coming up on them from behind or below, taking one bite, and then waiting for the animal to weaken from the loss of blood before moving in for the kill.
Economic Importance for Humans: Negative

None known, other than keeping tourists away from certain beaches and feeding on an occasional swimmer.
Economic Importance for Humans: Positive

There is a considerable market for the jaws with the teeth intact. In addition, the flesh and fins may be used for food, the liver for oil, the skin for leather, and the carcass for fish meal. It is also a popular game fish, as well as the subject of some very lucrative movies.
Conservation Status

The world population is unknown, as is any indication on whether total white shark numbers are increasing or decreasing. Many experts believe that the population of white sharks in South Australia has undergone a serious decline in recent years, but there are insufficient data to adequately estimate the the species' population size or to assess human impact on it. In 1989, the Threatened Fishes Subcommittee of the Australian Society for Fish Biology added the white shark to the Australian Threatened Fishes List in the "uncertain status" category.
Other Comments

Despite the world-wide attention given to the white shark through documentaries and articles, it remains one of the most poorly understood of the world's sharks. Unfortunately, the general population believes the white shark to be a mindless, random killers - man-eaters - largely because of movies like "Jaws" and other horror stories, and would feel safer if the species were eradicated. Exactly why sharks attack humans is unknown - possibly raw aggression, territoriality, or misidentification (i.e. the sillhoette of a person lying on a surfboard strongly resembles that of a seal or sea lion from below). What is known is that white sharks do not attack humans out of hunger; in other words, they do not attack people to eat them. Most attacks, even those that prove fatal, do not result in any consumption of the victim - whole or in part. If death occurs, it is likely to be the result of loss of blood, loss of tissue, or shock.

Joder, con tanta competencia no hay manera de ser un troll simpático en esta página web.
Bueno, tí"s, en serio, lucharé contra el nazi-onalismo catalán cuando en el resto del EStado luchen en serio contra el nazi-onalismo español.
