What is the largest shark ever found?


Sharks are fascinating creatures that have captivated the imagination of humans for centuries. With their sleek bodies and powerful presence, they are often portrayed as the apex predators of the ocean. One question that frequently arises is: what is the largest shark ever found? In this article, we will delve into the depths of the ocean to explore the answer to this intriguing question.

The Great White Shark

The Great White Shark (Carcharodon carcharias) is perhaps one of the most iconic and well-known shark species. It is renowned for its size and power, often being referred to as the “king of the ocean.” While it is indeed an impressive creature, the Great White Shark is not the largest species of shark ever discovered.

Size and Physical Characteristics

The Great White Shark typically reaches an average length of 4.6 to 6 meters (15 to 20 feet), with males generally being smaller than females. Its body is streamlined and muscular, allowing it to swim at high speeds and maneuver with agility. The shark’s powerful jaws are filled with rows of sharp, serrated teeth, perfectly adapted for hunting and tearing apart prey.

Feeding Habits

Great White Sharks are apex predators, meaning they are at the top of the food chain in their marine ecosystems. Their diet primarily consists of marine mammals such as seals and sea lions, as well as other fish species. These sharks are known for their ability to launch themselves out of the water, a behavior known as breaching, to catch prey.

The Whale Shark

While the Great White Shark is formidable in its own right, it is not the largest shark species. That title goes to the magnificent Whale Shark (Rhincodon typus). The Whale Shark holds the distinction of being the largest fish species in the world, and it is truly a sight to behold.

Size and Physical Characteristics

Whale Sharks are massive creatures, with some individuals reaching lengths of up to 18 meters (60 feet) or more. They have a distinct appearance, with a flattened head and a mouth that can open up to 1.5 meters (5 feet) wide. Their bodies are covered in a unique pattern of pale yellow spots and stripes, which serve as a form of camouflage in the water.

Diet and Feeding Behavior

Despite its enormous size, the Whale Shark is not a threat to humans. It is a filter feeder, meaning it primarily consumes plankton, small fish, and other microscopic organisms. The shark’s enormous mouth acts as a filter, allowing it to passively collect large volumes of water and filter out its prey using specialized gill rakers.

Other Large Shark Species

While the Great White Shark and the Whale Shark are the most well-known examples of large sharks, there are several other species that deserve mention.

The Basking Shark

The Basking Shark (Cetorhinus maximus) is the second-largest shark species, after the Whale Shark. It can reach lengths of up to 10 meters (33 feet) and is often found in colder waters. Despite its intimidating size, the Basking Shark is a gentle giant, feeding primarily on plankton and small fish.

The Megamouth Shark

The Megamouth Shark (Megachasma pelagios) is a relatively rare and mysterious species. It was first discovered in 1976 and is known for its distinctive large mouth and bulbous head. This shark can grow up to 5.5 meters (18 feet) in length and primarily feeds on plankton.

The Greenland Shark

The Greenland Shark (Somniosus microcephalus) is another contender for the title of largest shark species. It is a slow-moving and deep-sea dwelling shark that can reach lengths of up to 7 meters (23 feet). These sharks have an incredibly long lifespan, with some individuals estimated to be over 400 years old.

Frequently Asked Questions

  1. What is the largest shark ever recorded?

    The largest shark ever recorded is the Whale Shark, with individuals reaching lengths of up to 18 meters (60 feet) or more.

  2. Are all large sharks dangerous to humans?

    No, not all large sharks are dangerous to humans. Sharks such as the Whale Shark and Basking Shark are filter feeders and pose no threat to humans.

  3. How do scientists measure the size of sharks?

    Scientists typically measure the size of sharks by using specialized measuring tools and techniques. They often focus on the total length of the shark, from its snout to the tip of its tail.

  4. What is the average lifespan of a shark?

    The average lifespan of a shark varies depending on the species. Some species, like the Greenland Shark, have been known to live for over 400 years.

  5. Are there any extinct shark species that were larger than the Whale Shark?

    Yes, there have been several extinct shark species that were larger than the Whale Shark. One example is the Megalodon, an ancient shark that could reach lengths of up to 18 meters (60 feet) or more.

  6. Do sharks continue growing throughout their lives?

    Yes, sharks are known to continue growing throughout their lives. This is known as indeterminate growth, and it allows them to reach impressive sizes.

  7. How do sharks reproduce?

    Sharks reproduce through internal fertilization. Males have specialized reproductive organs called claspers, which they use to transfer sperm to the female during mating.

  8. Why are sharks important for marine ecosystems?

    Sharks play a crucial role in maintaining the balance of marine ecosystems. As apex predators, they help regulate the populations of other marine species and keep the ecosystem in check.

  9. Are there any conservation efforts in place to protect large sharks?

    Yes, there are various conservation efforts in place to protect large shark species. These include implementing fishing regulations, establishing marine protected areas, and raising awareness about the importance of shark conservation.

  10. Can humans swim with Whale Sharks?

    Yes, swimming with Whale Sharks is a popular activity in certain parts of the world. However, it is important to do so in a responsible and sustainable manner, ensuring the well-being of the sharks and their habitat.


In conclusion, the largest shark ever found is the awe-inspiring Whale Shark. With its massive size and gentle nature, it showcases the incredible diversity and magnificence of the ocean’s inhabitants. While the Great White Shark may hold the title of the ocean’s king, it is the Whale Shark that reigns supreme as the largest shark species. As we continue to explore the depths of the ocean, it is important to appreciate and protect these remarkable creatures for future generations to enjoy.
