Is a Whale Shark a Whale or a Shark?

Is a whale shark a fish or a mammal? Hmmmm… This is the ultimate question! With a face like a whale and a body like a shark, these seemingly frightening creatures are actually gentle giant sharks. That’s right, the Whale Shark is a slow-moving, filter-feeding carpet shark. Whale sharks are in no way related to whales. Although they are sharks, they are very docile and pose no real threats to humans. The whale shark is the largest shark in the world and can be found in tropical oceans in areas like the Maldives, the Philippines, and Mexico. They feed mainly on plankton and despite their gigantic size, whale sharks’ teeth are only 6 millimeters long!

Is it True that Each Whale Shark has a Unique Pattern?

Yes, it is. An interesting fact about whale sharks is that a whale sharks skin is completely unique, just like a human fingerprint. The patterns on its back allow researchers to run visual analytics to correctly identify and track individual whale sharks. How amazing is that?

Are Whale Sharks Endangered?

The International Union for Conservation of Nature (IUCN) Red List regards the species as one of the most vulnerable marine animals in the world and is currently listed as endangered on their Red List.

Although Indonesia, through its Ministry of Maritime Affairs and Fisheries, has enacted a law for whale shark conservation, the whale shark continues to be hunted for its highly prized fins and meat. The whale shark is listed on our most endangered sharks in the world list and efforts must be made to help raise awareness for these sharks.

Can a Whale Shark Eat a Human?

Whale sharks are really, really big. Their mouths can get up to five feet long, and they can suck in around 600 cubic meters of water every single hour. So swimming next to one might make you remember Pinocchio’s trip into the whale’s belly! And suddenly you might worry that that could actually happen to you. Could a whale shark swallow you by accident?

The answer is no, a whale shark could not swallow a human on purpose or by accident, as Dr. Craig McClain explains;

I know that the esophagus of a whale shark measures only inches across. The massive beast could not choke me down even if it preferred man meat to plankton.

Can you Swim with Whale Sharks?

Yes, you can swim with whale sharks. Swimming with these gentle giants is a life-changing experience, however, it must be done responsibly. The whale shark tourism’s industry in Mexico alone has increased significantly in the past several years, from just a few hundred tourists annually to over 12,000 per year.

This level of tourism puts great amounts of stress on the whale shark population, so we urge you to take a look at this great article written by WWF Travel Program on responsible whale shark tourism before diving or swimming with whale sharks.

What Threats do Whale Sharks Face?

Whale Sharks are very vulnerable to unsustainable fishing. Just like most shark species, whale sharks breed very slowly. This means that it takes a lot longer for their population to rebound after depletion. This makes them dangerously vulnerable to overfishing and also destructive fishing practices.

Whale sharks move at a very slow-moving pace. They swim at speeds of only 5 kilometers per hour but can dive up to 1,000 meters. Whale sharks prefer to swim in shallow waters of up to around 50 meters deep, this habit, unfortunately, makes them exceptionally vulnerable to ship collisions and fishing nets.

Most whale shark deaths are attributed to the global shark fin trade. The demand for shark fins is primarily driven by the market for shark fin soup. Shark fin soup is a luxury item which is popular in some Asian cuisines. Shark fins are not equal in value but are divided into a primary and secondary fin set with higher prices paid for the primary set. Dorsal fins from Whale Sharks and Basking Sharks are regarded as trophy fins fetching thousands of dollars apiece.

As many as 73 million sharks end up in the global shark fin trade every year.
