The tiburon ballena (Rhincodon typus) is a filter-feeding carpet shark and the largest known extant fish species. Despite its name, it’s not a whale at all. These gentle giants can grow up to 40 feet long (sometimes even more!) and weigh as much as 20 tons. Their massive mouths, unique spot patterns, and calm demeanor make them a favorite among divers and snorkelers.
Whale Shark Background: Where Do They Come From?
Whale sharks are found in tropical and warm-temperate seas around the world. They’re known for their long migrations, often traveling thousands of miles in search of food. Their distinctive white spots and stripes are like fingerprints—no two are exactly alike.
Are Whale Sharks Whales or Sharks? Clearing Up the Confusion
It’s a question that comes up all the time: are whale sharks whales or sharks? The answer might surprise you.
The Truth About the Tiburon Ballena
Despite their name and enormous size, whale sharks are not whales. They’re sharks—true fish, not mammals. Unlike whales, which breathe air and nurse their young, whale sharks have gills and lay eggs internally (a process called ovoviviparity). They’re more closely related to great white sharks than to any whale.
Quick Comparison
- Whale:Â Mammal, breathes air, warm-blooded, gives live birth, nurses young.
- Shark (including tiburon ballena):Â Fish, breathes through gills, cold-blooded, lays eggs or gives birth to live young (depending on species), no nursing.
The Teeth of Whale Shark: Tiny but Mighty
When you picture a shark, you probably imagine rows of razor-sharp teeth. But the teeth of whale shark are a little different—and a lot less scary.
What Do Whale Shark Teeth Look Like?
Whale sharks have thousands of tiny teeth—up to 3,000 in their mouths! But here’s the twist: they don’t use them for eating. Instead, they’re filter feeders, sucking in huge gulps of water and straining out plankton, small fish, and other microscopic goodies.
How Do They Eat?
Instead of biting or tearing, the tiburon ballena opens its massive mouth and lets water (and food) flow in. Special filter pads trap the food, and the water is expelled through the gills. It’s a gentle, almost graceful way to eat—very different from the hunting style of other sharks.
Real-Life Example
A diver once shared, “I swam next to a tiburon ballena in Mexico, and I could see its tiny teeth when it opened its mouth. It was like looking into a giant vacuum cleaner—completely harmless, but absolutely mesmerizing.”
What Aquariums Have Whale Sharks? Where to See Them Up Close
Not everyone can travel to the open ocean to see a tiburon ballena in the wild. Luckily, a few aquariums around the world offer the chance to see these giants up close.
Top Aquariums With Whale Sharks
- Georgia Aquarium (Atlanta, USA):Â The only aquarium outside Asia with whale sharks. Their Ocean Voyager exhibit is world-famous.
- Okinawa Churaumi Aquarium (Japan):Â Home to several whale sharks in a massive tank.
- Kaiyukan Aquarium (Osaka, Japan):Â Another top spot for seeing whale sharks in captivity.
Is It Ethical to Keep Whale Sharks in Aquariums?
This is a hot topic among marine biologists and animal lovers. While aquariums can help with research and education, keeping such large, migratory animals in captivity is controversial. Many experts believe that the best way to experience a tiburon ballena is in its natural habitat, where it can roam free.
The Life of a Tiburon Ballena: Habits, Migrations, and Mysteries
The more we learn about the tiburon ballena, the more mysterious it seems. Scientists are still uncovering the secrets of their migrations, breeding habits, and even their lifespan.
Where Do Whale Sharks Live?
Tiburon ballena are found in warm waters all over the world, from the coasts of Mexico and the Philippines to the Indian Ocean and beyond. They often gather in large numbers at certain times of year, following plankton blooms and fish spawning events.
How Long Do Whale Sharks Live?
Estimates vary, but most experts believe whale sharks can live 70–100 years or more. That’s a long time to wander the world’s oceans!
How Do They Reproduce?
Very little is known about whale shark reproduction. Females give birth to live young, but sightings of baby whale sharks are extremely rare. This mystery only adds to their allure.
The Gentle Giant: Why the Tiburon Ballena Is Loved Worldwide
Despite their size, tiburon ballena are known for their gentle nature. They pose no threat to humans and are often curious about divers and snorkelers.
Swimming With Whale Sharks: A Life-Changing Experience
Many travelers describe swimming with a tiburon ballena as a once-in-a-lifetime adventure. The feeling of being dwarfed by such a massive, peaceful creature is hard to put into words.
User Quote
“I was nervous at first, but the tiburon ballena just glided past me, completely uninterested. It was like swimming next to a moving mountain—calm, beautiful, and unforgettable.”
Conservation Status: Protecting the Tiburon Ballena in 2025
Sadly, the tiburon ballena is listed as endangered. Overfishing, boat strikes, and habitat loss threaten their survival.
Main Threats
- Fishing:Â Whale sharks are sometimes caught accidentally in fishing nets.
- Boat Collisions:Â Their slow, surface-swimming habits make them vulnerable to boats.
- Pollution:Â Plastic and other pollutants can harm their food sources.
Conservation Efforts
International protections, marine reserves, and responsible tourism are helping, but there’s still much work to be done. Supporting organizations that protect the tiburon ballena is one way you can help.

Tourism centered around the tiburon ballena can be a double-edged sword.
Pros
- Raises Awareness:Â Seeing these animals up close inspires people to care about ocean conservation.
- Supports Local Economies:Â Responsible tourism can provide income for coastal communities.
Cons
- Disturbance:Â Too many boats and swimmers can stress the animals.
- Unethical Practices:Â Some operators ignore guidelines, putting both sharks and people at risk.
How to Choose a Responsible Tour
Look for operators who follow strict guidelines: limit group sizes, avoid touching the animals, and keep a respectful distance.
