A Great White Shark has a life expectancy of about 70 years. The Great White is one of the world’s largest predatory fish, and it belongs to the Lamniformes order of sharks.
Both due to misunderstanding and because of the shark’s propensity to attack swimmers, surfers, and divers, this predator remains one of mankind’s most feared sharks.
The physical characteristics, habitats, diets, and breeding habits of sharks in general are all described in detail by Great White Sharks.
Great whites have a lifespan that is almost as long as humans’ — up to 70 years.
Lifespan Of Great White Sharks
According to study co-author Li Ling Hamady, an oceanography graduate student at Woods Hole Oceanographic Institution in Massachusetts, white sharks in the northwest Atlantic are significantly older than previous age estimates, with some of them aged over 23 years old.
The data, which will be published in the journal PLOS ONE on January 8th, demonstrate that apex predators take longer to develop than was previously thought and are thus more susceptible to overfishing.
It’s impossible to figure out a great white shark’s age. Age estimations are commonly made using shark teeth, ear bones, vertebrae, and bony rods in the skeleton. These body parts retain layers of tissue that are laid out in light and dark stripes, similar to tree rings, because they grow throughout a shark’s life.
Previous studies assumed that each stripe corresponded to yearly growth throughout a shark’s life, which isn’t always the case. It’s therefore difficult to differentiate between these bands because they may be narrow or colorful.
Instead, Hamady and her colleagues took advantage of the fact that huge amounts of carbon-14, a radioactive isotope or variant of carbon with more neutrons than the typical form, were produced during nuclear bomb testing between the mid-1950s and early 1960s.
Tissue from that time period shows a distinct rise in the levels of carbon-14 when compared to the background levels found in the environment because carbon-14 fell from the atmosphere into the ocean and was absorbed by marine creatures.
From 1967 to 2010, the team examined the radiocarbon in four female and four male large white shark vertebrae recovered in the Atlantic Ocean.
Why Does A Longer Lifespan Make Great White Sharks More Vulnerable?
Great white sharks were previously thought to live around twenty years, according to scientists, but new research suggests that they may live anywhere from fifty to seventy years. Great white sharks grow up more slowly as a consequence, and they have a longer reproductive cycle.
Fishermen have been capturing and killing large white sharks while they’re still young, prompting the International Union for Conservation of Nature to classify them as “vulnerable.”
While some countries have banned big white shark hunting, others allow individuals to capture them for their fins or teeth.
What Do Great White Sharks Look Like?
The ventral (under) side of the great white shark is white, while the dorsal (over) side is gray. Since each hue corresponds to the angle from which the shark is seen, this contrast enhances the shark’s stealth. The darker gray side of the great white helps it blend in with the ocean’s darker depths when viewed from above.
The lighter white side of the iceberg blends in more with the water’s lighter surface when viewed from below. Because it absorbs a lot of force during attacks, the large white has a huge nose as well.
The Difference Between Males And Females
Depending on size and sex, Great White Sharks rule. Females are bigger than males, thus they have the upper hand. They generally do not battle one another, but instead employ ceremonies to protect themselves from impending dangers and rivalry. Despite the appeal of these ceremonies, biting is still a last resort effort to establish power, even if push comes to shove.
The Rundown on Great White Sharks
The great white shark, scientifically known as Carcharodon carcharias, is one of more than 450 species of sharks in the world.
Because they are at the top of the ocean’s food chain, they are considered to be an apex predator. Great white sharks may grow to be 20 feet long, but the majority of them are much shorter. Men measure 11-13 feet in length, while females measure 15-16 feet.
Except for Antarctica, they can be found in seas all around the globe. Coastal areas are where they are most common. The big white shark is an important member of the ocean’s ecosystem, despite its fearsome reputation. They also keep populations of sea lions and elephant seals in check because of their massive size. When a big white shark is present, the oceans are in equilibrium.
So, how long do these enormous hunters live? Let’s talk about how long the largest white sharks live and how long they live.
How Can We Help Save The Great White Sharks?
These creatures do play an important role in the ocean, even if you may not want to encounter a great white shark face-to-face anytime soon. They influence the populations of other marine creatures, such as sea lions and seals, as apex predators.
We strive to keep our magnificent white sharks (as well as the seas they live in) healthy by donating to charities that aid them at Cape Clasp. The following are some of the organizations we support:
Since 2013, the Atlantic White Shark Conservancy (AWSC) has been working to study and protect the great white sharks of the Atlantic Ocean, particularly off the coast of Massachusetts.
The development of the Sharktivity app, which helps people keep track of information on great white shark sightings and movements, is one of this organization’s greatest achievements.
Beneath the Waves works with a range of vulnerable or endangered species, but they have taken an particular interest in our great white sharks since their founding in 2013. New research, new technologies, and innovation are all part of the extensive team’s efforts to protect ocean life in a variety of ways.
They collaborate closely with decision-makers and local governments in regions where great white shark activity may occur, while carrying out their own research on marine protected areas or endangered species.
Another conservation organization focused on endangered species, however this time focusing on threatened sharks like great whites, is Saving the Blue: Saving the Blue.
Saving the Blue is committed not only to improving awareness of the value of marine life in future generations, but also to ensuring that future generations understand what they may do to help.
The Shark Research & Conservation Program was founded in 2010 with the goal of advancing knowledge about our endangered sharks as well as equipping future generations with the tools they need to help these species.
Great white sharks hunt, survive, and are even attacked off the coast of South Africa, according to their scientific studies.
The Bimini Sharklab, which has been operating since 1990 and is situated near the Bahamas island of South Bimini, is another non-profit that aims to aid further research on endangered sharks.
Their study gives more knowledge about our sharks’ biology and how they function in the ecosystem, which is valuable. Many scientists, as well as the general public, may not be aware of the full significance of sharks in the oceans, and Bimini Sharklab strives to educate them.
The Average Great White Shark Life Cycle
How do sharks transition from being terrified infants to incredibly terrifying predators? Fertilization, incubation, gestation, pups, subadults, and adults are the five life stages of great whites classified by scientists. Now, let’s look into each of the life stages in depth.
Fertilization serves as the beginning of a shark’s life. Although researchers and scientists seldom witness mating among sharks, it is well-known. The female egg receives internal fertilization. In mammalian species, the male’s pelvic fin is what is used to fertilize the eggs, and it is most closely related to a penis.
Sharks go through incubation after being fertilized. Sharks lay their eggs inside their bodies in the vast majority of cases. For up to two years, the female shark will be pregnant. Cannibalism is surprisingly common in certain shark species, especially when the initial pup devours the remainder of the eggs while still inside its mother. This activity is referred to as oophagy.
Great White Sharks Eat Different Prey Throughout Their Lifespan
Tuna, rays, whales, porpoises, dolpins, seals, sea lions and sea otters are all eaten by great white sharks. Since their jaws are too weak to deal with the stresses required to attack huge prey, they prey mostly on fish during their adolescence, before they begin to grow.
Their jaw cartilage mineralizes sufficiently to withstand the bite of biting into bigger prey species when they reach a length of roughly 3 meters (9.8 feet). When they grow to be 4 meters (13 feet) in length, they commence attacking gigantic marine creatures.
Are Great White Sharks Endagered?
The great white shark is currently listed as an endangered species on the CITES (Convention on International Trade in Endangered Species) list. Humans, on the other hand, have had a significant influence in the endangerment of these animals, as we hunt them out of fear of being attacked by them.
Common Factors That May Negatively Impact the Great White Shark Lifespan
The great white shark occupies the top of the food chain as an apex predator. As a result, there isn’t much in the ocean that can harm or chase down humans. The only natural enemy of these creatures is the killer whale, which lives in the sea. So, read on to learn about what may be deadly to a big, threatening animal like a great white.
How Do Great White Sharks Kill Their Prey?
The great white shark’s teeth are well-known for being used to murder prey. The shark shakes its head like a dog, tearing off portions of flesh and swallowing them all at once when it seizes prey between its razor-sharp saws. A 14-kilogram portion of flesh can be ripped away by a powerful shark’s bite. This is a frequent cause of death for human attacks.
The shark does not always intend to harm the individual — instead, after one taste, it usually departs the victim alone since it dislikes the flavor. Yet, a single bite may do such significant harm that the victim is seriously wounded or killed.
Since these two elements aid to conceal its assault, the Great White Shark often approaches victims from below and favors filthy water or poor illumination. Except for dolphins and porpoises, it attacks prey most frequently when they are near the water’s surface.
Why are there exceptions? Dolphins and porpoises, on the other hand, have a unique skill known as echolocation that allows them to ‘see’ everything in their immediate surroundings. The shark would risk being detected and losing out on its meal if it was to attack them from below.
As a result, Great White sharks descend on dolphins and porpoises from above. Spy-hopping is a behavior in which a shark raises its head out of the water to inspect potential prey and maybe even smell it. This kind of shark has also been spotted doing it.
Are Great White Sharks Warm Blooded?
The technical warm-bloodedness of the Great White Shark distinguishes it from other sharks. Each side of the shark’s body is covered in a web of veins and arteries that help to warm the blood and preserve heat. The temperature inside the container is kept higher than that of the water.
Instead of wasting energy attempting to warm up its body, the shark can spend it on hunting and swimming. The Great White is an endothermic poikilotherm, which means that its internal body temperature is not consistent but maintained constant regardless of the water’s temperature.
While there are many endangered marine species in the deep blue, great white sharks are one of the most misrepresented.
Many individuals may not be aware of the critical role they play in keeping other marine creature populations in check, or how they help to keep an healthy ocean ecosystem. Every time we sell something at Cape Clasp, 15% of the money goes to charities like the ones listed above.
Several shark-friendly jewelry, such as the Great White Clasp or our tiny Shark Fin necklace, are included in our collection. You may also directly contribute to one of the charities we’ve just mentioned.
