The basking shark is a fascinating creature that inhabits several regions worldwide. Known for its massive size, unique feeding behavior, and gentle nature, this shark has gained widespread popularity among both marine biologists and the general public. However, there is still much to learn about this elusive animal. Here are some astonishing facts that you didn’t know about the basking shark:

1. The largest fish in the Atlantic Ocean

The basking shark is the largest fish species found in the Atlantic Ocean. It can grow up to 32 feet long and weigh up to 5,000 pounds! Its massive size is due to its planktonic diet, which requires the shark to consume enormous quantities of water to filter out tiny organisms.

2. Filter-feeder extraordinaire

The basking shark possesses large gill rakers that extend out from its mouth, which it uses to filter plankton from the water. It can filter up to 2,000,000 liters (528,000 gallons) of water in a single hour.

3. They prefer cold water

The basking shark prefers to live in cold waters, with temperatures ranging from 6-20°C (43-68°F). This preference leads them to inhabit the North Atlantic, the Irish Sea, the English Channel, the Bay of Biscay, and the Pacific off the coast of Japan.

4. Migratory creatures

The migratory habits of the basking shark are still largely unknown. However, researchers believe that basking sharks move to warmer waters during the winter months and return to colder waters during the summer to feed. Interestingly, the basking sharks found in the Atlantic are genetically distinct from those found in the Pacific.

5. Their liver is the largest of any fish

The liver of the basking shark can account for approximately 25% of its total body weight, making it the largest of any fish. The liver contains large amounts of oil that help regulate the shark’s buoyancy.

6. Low reproductive rate

Basking sharks have a reproductive cycle that lasts for several years, with females only giving birth every two to four years. Moreover, basking sharks have low reproductive rates, with females giving birth to only four to six pups during their lifetime.

7. They can live up to 50 years

Despite their slow reproductive cycle, basking sharks can live up to 50 years. However, because of overfishing and habitat loss, the basking shark is currently classified as a vulnerable species by the International Union for Conservation of Nature (IUCN).

In conclusion, the basking shark is a fascinating animal that still holds many secrets waiting to be uncovered. From their massive size to their unique feeding behavior, the basking shark continues to amaze researchers and awe the public. It is essential to raise awareness about this magnificent creature and the various conservation efforts needed to protect it.
