1. English name and scientific name of the great white shark

 

The English name for the great white shark is Great White Shark Its name, meaning "Great White Shark," comes from its massive size and white belly. In English-speaking countries, it is also known by the nickname "Man-Eater Shark," a name largely influenced by the movie "Jaws" (directed by Steven Spielberg).

Its scientific name is Carcharodon carcharias, named by Linnaeus in 1758. The genus Carcharodon contains only one extant species: the great white shark.

 

 

2. Where do great white sharks live?

Great white sharks do not inhabit only certain countries, From subtropical to subarctic regions, the oceans of the world It is widely distributed in [location].

Main habitats

 

• West Coast of the United States (Especially along the California coast)
• South Africa (Around False Bay)
• Australia and New Zealand
• mediterranean
• Seas off the coast of Japan (From Hokkaido to Kyushu)
• North Atlantic (Records exist as far as the coasts of Canada and Alaska)

A study published in 2009 found that The deep sea between Mexico and Hawaii A sea area where great white sharks gather has been identified and named the "White Shark Cafe" by researchers. Multiple individuals gather in this area for a certain period of time, and behaviors related to breeding have been observed.

They tend to gather around breeding grounds for seals and sea lions, and in False Bay, South Africa, they are known for the spectacular predation scene called "breaching," where they leap out of the water.

 

 

3. Morphology and physical characteristics of the great white shark

Body structure

The body shape of a great white shark is Sturdy, streamlined spindle shape It has a crescent-shaped tail fin with almost equal length at the top and bottom. This tail fin shape is optimized for high-speed swimming, and it has been recorded to reach speeds of over 40 kilometers per hour. Furthermore, when it gains momentum, it has been observed to leap high enough to completely out of the water.

tooth structure

Great white shark teeth It is an equilateral triangle with a length of approximately 7.5 centimeters. They have saw-like serrations (serrated edges). These teeth are used to cut through skin and muscle, and it is said that they can tear off a chunk of meat weighing about 14 kilograms in a single bite. They have three rows of teeth, and even if a tooth falls out, the tooth row behind it immediately moves forward to make room. Their teeth can be replaced multiple times.

body temperature regulation

Great white sharks Paranormal activity They possess a capillary heat exchange system called a cyst, which allows them to maintain a body temperature higher than the surrounding seawater temperature. This enables them to maintain high athletic performance even in cold waters. This characteristic is very rare among cartilaginous fish and is found only in some shark species, such as the mako shark.

 

4. The Ecology of the Great White Shark: Diet, Behavior, and Reproduction

eating habits

Great white sharks Completely carnivorous The main prey is as follows:

• Marine mammals such as seals, fur seals, and walruses
• Dolphin
• Large fish (such as tuna)
• squid
• seabird
• whale carcass

It is believed that they become full after eating about 30% of their body weight, and they may not eat for a long period after catching a large prey.

Hunting tactics

Great white sharks often employ an "ambush" hunting style, conserving energy by moving their tail fin slowly in areas with abundant food, and then accelerating to launch a surprise attack the moment prey approaches.

A 2022 study found that great white sharks They learn to hunt by acting together with other individuals. This behavior has been confirmed through bio-logging studies. Although sharks are often thought to be solitary creatures, they actually exhibit social behaviors such as sharing prey with other members of their group.

breeding

Great white sharks Ovoviviparous The fetus, which hatches from the egg inside the womb, grows by feeding on unfertilized eggs. Furthermore, it has been confirmed that the uterine milk is secreted in the early stages of pregnancy, a characteristic currently found only in great white sharks among shark species.
The number of baby sharks born in a single birth is 2-15 fish They measure 1.2 to 1.5 meters in length. From the moment they are born, they live as independent predators.

 

5. The lifespan of the great white shark

The lifespan of the great white shark was unknown for a long time, but thanks to advances in research, it is now known. Over 70 years old It is believed that they may live longer. Their lifespan was previously estimated at around 25 years, but this has been significantly revised upwards by analyzing the growth rings of the spine. This would put them on par with large mammals such as blue whales.

Growth is extremely slow, with males taking about 10 years and females about 15 years to reach sexual maturity. As a result, population recovery is slow, making them vulnerable to overhunting and habitat destruction.

 

6. Great White Shark vs. Orca – Which is stronger?

Which is stronger, a great white shark or an orca? This is a question that interests many people.

In conclusion, In actual encounters, orcas often have the upper hand. It has been reported that...

Why orcas are superior to great white sharks

 

• Intelligence and collaboration Orcas act in coordinated groups and strategically hunt down their prey. Great white sharks also possess a certain level of intelligence, but it is no match for that of orcas.
• Induction of a state of feigned death Orcas possess the ability to induce "tonic immobility," a state of feigned death where they flip sharks over completely. Great white sharks in this state are unable to resist.
• physique Large orcas can sometimes be larger than great white sharks.

Multiple pieces of evidence have been found in South Africa and the west coast of the United States indicating that orcas have actually preyed on great white sharks. Great white sharks that encounter orcas have also been observed to disappear from the area for extended periods.

However, great white sharks are not without natural predators; larger individuals may prey on smaller individuals of the same species or other larger sharks.

 

 

7. What is the most ferocious shark in the world?

From the perspective of danger to humans, Great white shark, tiger shark, bull shark These three species are widely known as the "world's three most dangerous sharks."

 

• Great white shark The number of traffic accidents resulting in injuries and fatalities is the highest on record. Between 1876 and 2004, 224 traffic accidents resulting in injuries were confirmed, of which 63 were fatal.
• Tiger shark They have a habit of eating anything without distinguishing between different species, and they are also known to attack humans.
• Bull shark They can also enter rivers, and accidents have occurred in freshwater areas.

In terms of sheer ferocity, all three species are at a high level, but in terms of the number of accidents involving humans... Great white sharks are the most numerous in the world. I have the record.

 

8. Why do great white sharks attack humans?

Several theories have been proposed regarding why great white sharks attack humans.

The most likely theory: "Misidentification theory"

Great white sharks primarily feed on marine mammals such as seals and sea lions. When a surfer is seen from above the water on their board, their outline can sometimes closely resemble that of a seal. The same is true when a person wearing a wetsuit moves their flippers.

A behavior known as "test bite" is also known, where great white sharks sometimes bite their prey once to determine if it is indeed prey. Humans are not their preferred food because they are low in fat, so they may release the shark after biting, but even that single bite carries the risk of inflicting a fatal injury.

Situations that make accidents more likely

 

• While surfing (the silhouette visible on the water's surface resembles a seal)
• During fishing operations such as helmet diving
• While swimming at the beach (especially in the evening and morning)

Prevention points

 

• Do not approach dangerous areas where sightings have been reported.
• Avoid accessories that reflect light and swimsuits with strong contrasts in color.
• Do not swim if you are bleeding.
• Avoid long-distance swimming alone.

9. Great White Sharks and Japan: Sightings and Incidents

Great white sharks also inhabit the waters around Japan. Fishing records from Hokkaido to Kyushu There is.

Main records in Japan

 

• May 1985 A tuna measuring approximately 540 cm in length and weighing 1,200 to 1,400 kilograms was caught in a large tuna net off the coast of Todohokke Village, Hokkaido (now Hakodate City). This was the first recorded catch of this species in Hokkaido.
• March 1992 Off the coast of Horie-cho, Matsuyama City, Ehime Prefecture (Seto Inland Sea), a diver fishing for pen shells was attacked and killed by a great white shark. Dental analysis identified the shark as a great white approximately 5 meters long. This is the first case in Japan where a shark attack has been recognized as a work-related injury.
• April 1995 A man fishing for surf clams off the coast of Irago, Aichi Prefecture, was killed when a great white shark bit off his right arm and abdomen. The shark is estimated to have had a jaw width of over 40 centimeters and a total length of approximately 5 meters.
• July 1999 A great white shark, measuring approximately 5.3 meters in length and weighing approximately 3 tons, was captured near Murozumi Beach in Hikari City, Yamaguchi Prefecture.
• October 2005 A 4.8-meter-long male carcass was discovered in the Chidori Canal in Kawasaki City, Kanagawa Prefecture. It is currently on display as a taxidermied specimen at Kawasaki Marien.

10. Great white sharks and Australia

Australia is one of the regions in the world with the highest number of great white shark attacks. Between 1791 and 2006, there were 668 shark attacks in Australia alone, resulting in 191 deaths.

Great white sharks off the coast of Australia are famous for their spectacular leaps, known as "breaching," to catch prey. Along with South Africa, this region is known for having a large number of highly active great white sharks.

In Australia, attempts have been made to keep great white sharks in aquariums, with Ocean World Manly having a record of keeping them for up to 10 days in 1968, 1974, and 1984, and Underwater World for 2 days in 1998. However, none of these attempts have resulted in long-term keeping.

 

11. Is it possible to see great white sharks in aquariums?

Currently (as of 2026), There are no aquariums in the world that have live great white sharks on display.
Great white sharks need to constantly swim to breathe, and in most cases, they die within a short period of time due to stress from the aquarium environment.

Main breeding records (worldwide)

 

facility	period	overview
Monterey Bay Aquarium (USA)	Maximum 198 days	A young female individual. It was later released into the sea.
SeaWorld San Diego (USA)	up to 16 days	Multiple individuals between 1969 and 1981
Okinawa Churaumi Aquarium (Japan)	3 days	January 2016. It was the world's first exhibit of an adult specimen, but it died.

In Japan, in addition to the Okinawa Churaumi Aquarium, there are records of them being kept at the Shimane Prefectural Aquarium (2002, 4 days) and the Oita Marine Palace Aquarium "Umitamago" (2004, 1 day).

Mysterious bite marks found on a great white shark's body

In April 2026, a photograph of a great white shark taken in 2019 off the coast of Mexico by Azerbaijani photographer Jalil Nadjafov attracted renewed attention. The photograph shows a huge bite mark on the side of the shark's body, which marine conservation science expert Michael Domeyer believes to be the result of an attack in the struggle for survival, and that the wound is already healing.

Impact of global warming on great white sharks

A study published in the scientific journal Science in 2026 suggests that mesothermic fish species, such as great white sharks (which maintain a body temperature higher than the seawater temperature), may be at risk of overheating due to rising seawater temperatures. Because great white sharks have a high body temperature, there are concerns that the energy cost of regulating their body temperature will increase in warmer seawater. Future research will be closely watched to determine whether global warming will affect the population and distribution of great white sharks.

 

summary

The great white shark is one of the world's most formidable marine predators, inhabiting oceans worldwide. Its English name is Great White Shark, and its scientific name is Carcharodon carcharias. It can grow to over 6 meters in length, swim at speeds exceeding 40 kilometers per hour, and live for over 70 years. In confrontations with orcas, it is often at a disadvantage in both size and intelligence, giving orcas a certain advantage in the actual ecosystem. It also inhabits waters near Japan, and there have been past incidents involving human casualties. To date, there are no successful long-term captivity examples of great white sharks in aquariums worldwide, and it remains a mysterious creature.
