If you're feeling fancy, great white sharks, or *Carcharodon carcharias* are some of the most famous sharks out there. Here's what makes these ocean giants so fascinating.
How Great White Sharks Look

Great white sharks have a look that’s hard to miss. They’ve got these big, torpedo-shaped bodies with sharp, pointy snouts and rows of serrated teeth that mean business. Their coloring is perfect for their environment —they’re grayish-blue on top, which helps them blend into the dark ocean when viewed from above, and white underneath, which makes them harder to spot from below against the brighter surface.
How Big Great White Sharks Get
These sharks are massive. Most adult Great Whites are between 15 to 20 feet long (that’s about 4.5 to 6 meters), but some have been reported to reach over 23 feet (7 meters). They can weigh several tons, with the females generally being larger than the males.
Where Great White Sharks Live
Great whites are found all over the world’s oceans, especially along the coasts of North America, South America, Africa, Australia, and parts of Asia and Europe. They prefer the cooler waters of temperate and subtropical regions.
What Great White Sharks Eat
As apex predators, great white sharks sit at the top of the ocean food chain. Their menu includes marine mammals like seals, sea lions, and dolphins, as well as big fish like tuna and other sharks. They have a seriously strong bite and can take down prey much bigger than themselves.
How Great White Sharks Behave
Great white sharks are known for their hunting skills. They often surprise their prey by ambushing from below and might even breach the surface in a spectacular attack. Despite their fearsome reputation, they’re also curious creatures, sometimes checking out boats or other objects to see what’s up.
Great White Sharks - Conservation and Misconceptions
Unfortunately, the International Union for Conservation of Nature (IUCN) classifies great white sharks as vulnerable. Overfishing, habitat loss, and accidental catches are some reasons the sharks are at risk. Efforts are being made to protect them, and many areas have laws in place to help with conservation.
And let’s clear something up—despite what movies might have you believe, great white sharks aren’t out to get us. Shark attacks on humans are actually pretty rare, and they’re usually not fatal. Most of the time, if a shark bites a person, it’s out of curiosity or self-defense, not because they see us as a tasty snack.
Why Great White Sharks Matter
Great white sharks are crucial for keeping ocean ecosystems in balance. As top predators, they help control the populations of other species, which is vital for a healthy ocean. So, understanding and protecting these incredible creatures is super important for the health of our oceans.
How Long Do Great White Sharks Live
Great white sharks have a relatively long lifespan, especially for fish. Recent research suggests that they can live up to 70 years or more, making them one of the longest-lived cartilaginous fish species.
Average Lifespan:
While the lifespan can vary, great white sharks generally live between 40 and 70 years.
Growth and Maturity
They reach sexual maturity relatively late in life. Males typically mature around 26 years old, while females usually reach maturity around 33 years old.
Aging Studies
The estimation of great white shark age has improved with better techniques, such as counting growth rings in their vertebrae, similar to counting tree rings. These growth rings were initially thought to represent one year per ring, but later studies revealed that they may form more slowly, realizing that great whites live much longer than previously believed.
Their long lifespan, late maturity, and low reproductive rates make great white sharks particularly vulnerable to threats like overfishing and habitat loss, which is why they are considered a vulnerable species.
Problems WithGreat White Sharks In Captivity
Great white sharks require vast amounts of space to swim continuously, as they must keep moving to breathe. They also have complex behavioral needs and often suffer from stress, which can lead to poor health or death when kept in confinement. Because of these challenges, most aquariums focus on other shark species better suited to captive environments.
While some aquariums have temporarily housed great whites, there is currently no facility in the world that keeps them long-term, and the ethical considerations and logistical challenges make it unlikely that this will change in the near future.
1. Monterey Bay Aquarium (California, USA)
The Monterey Bay Aquarium is one of the few places that has successfully kept great white sharks in captivity, though only for limited periods. The aquarium housed several young great whites over the years, with the longest stay being about 198 days. They eventually released these sharks back into the wild, as they struggled to thrive in captivity.
2. Okinawa Churaumi Aquarium (Okinawa, Japan)
In 2016, the Okinawa Churaumi Aquarium briefly housed a great white shark. Unfortunately, the shark only survived for a few days, highlighting the challenges of keeping these animals in captivity.
3. SeaWorld (California, USA)
SeaWorld has attempted to display great white sharks in the past, though these attempts were short-lived, with the sharks typically not surviving long in captivity.
4. Steinhart Aquarium (California, USA)
The Steinhart Aquarium in San Francisco was one of the first to attempt keeping a great white shark in captivity back in the 1950s. However, the shark did not survive long, a common outcome for great whites in captivity.
5. Tokyo Sea Life Park (Tokyo, Japan)
Tokyo Sea Life Park has also made attempts to keep great white sharks. As with other aquariums, their efforts were met with limited success, and the sharks were only kept for short periods.
