The biggest fish in the world is an awe-inspiring creature that captures the imagination of both scientists and laypeople alike. These massive creatures can grow to be over 40 feet long and weigh more than 20 tons, making them some of the largest animals on the planet. Despite their enormous size, however, these gentle giants are filter feeders that subsist on tiny plankton and other microscopic organisms. While sightings of these incredible creatures are rare, they continue to fascinate and captivate those lucky enough to catch a glimpse of them in the wild.

Discovering the World’s Biggest Fish: Name and Habitat
The Whale Shark
The world’s biggest fish is the whale shark (Rhincodon typus), which can grow up to 40 feet long and weigh up to 20 tons. Despite its name, the whale shark is not a whale but a fish, and it belongs to the family of carpet sharks. The whale shark has a distinctively flat head with a wide mouth that can open up to five feet wide, allowing it to filter feed on plankton and small fish.
The whale shark inhabits warm tropical waters around the world, including the Indian Ocean, Pacific Ocean, and Atlantic Ocean. It prefers areas with high plankton concentrations, such as near coral reefs or upwelling zones where nutrient-rich water rises from deep below the surface. The whale shark is known for its long-distance migrations, and some individuals have been tracked traveling more than 8,000 miles across oceans.
Other Large Fish Species
- Basking Shark (Cetorhinus maximus)
- Giant Oceanic Manta Ray (Manta birostris)
- Tiger Shark (Galeocerdo cuvier)
- Goliath Grouper (Epinephelus itajara)
The largest recorded whale shark was caught off the coast of Pakistan in 1947 and measured over 41 feet long!
The Enormous Size and Unique Physical Features of the World’s Biggest Fish
The size of the whale shark is truly enormous. To put it into perspective, a fully grown adult whale shark is larger than most school buses. Its mouth alone can fit a small car inside, and its body is covered in unique white spots that form distinct patterns like fingerprints.
In addition to its size, the whale shark has several unique physical features that set it apart from other fish species. Its skin is up to four inches thick and contains dermal denticles, which are similar to tiny teeth and help protect the shark from predators. The whale shark also has five large gill slits on each side of its head, which allow it to extract oxygen from the water as it swims.
The spots on a whale shark’s skin are not just for decoration; they are actually unique to each individual and can be used for identification purposes.
Diving into the Diet and Hunting Techniques of the World’s Biggest Fish
The whale shark is a filter feeder, which means it feeds by swimming with its mouth open and filtering plankton and small fish out of the water. It can consume up to 66 pounds of food per day! Despite its enormous size, the whale shark has a relatively small throat and cannot swallow anything larger than a basketball.
Unlike other sharks that use their sharp teeth to catch prey, the whale shark relies on suction feeding. It opens its mouth wide while swimming towards its prey, creating a low-pressure zone that sucks in water along with plankton or small fish. The water then passes through special gill rakers that filter out food particles while expelling excess water through its gills.
The whale shark’s feeding behavior can create a vortex that attracts other fish, which can also get caught in its mouth and become unintended prey.
Human Impact on the Population of the World’s Biggest Fish and Conservation Efforts to Protect It
Threats to Population
The whale shark population has been declining due to various human activities, including overfishing, accidental capture in fishing nets, and boat strikes. In some countries, the whale shark is also hunted for its meat and fins, which are considered a delicacy or used in traditional medicine.
To protect the whale shark population, several conservation efforts have been implemented around the world. These include banning hunting and trade of whale sharks in many countries, establishing marine protected areas where they can thrive without interference from humans, and promoting responsible tourism that does not harm their natural habitat.
The Philippines was the first country to declare the whale shark a protected species in 1998.
The Vital Role of the World’s Biggest Fish in Its Ecosystem and Importance of Maintaining a Healthy Population
The whale shark plays a crucial role in its ecosystem as a top predator that helps maintain balance among other species. Its filter feeding behavior also helps distribute nutrients throughout the water column, supporting other marine life such as plankton and small fish.
Importance of Healthy Population
Maintaining a healthy population of whale sharks is essential not only for their own survival but for the overall health of our oceans. As apex predators, they help regulate populations of other species and maintain healthy ecosystems. By protecting them, we can also protect other marine life that rely on them for food and habitat.
The whale shark is considered a keystone species, meaning that its presence or absence can have a significant impact on the entire ecosystem.
In conclusion, the biggest fish in the world is the whale shark, which can grow up to 40 feet long and weigh over 20 tons. Despite its massive size, this gentle giant feeds on plankton and poses no threat to humans.

What is the largest fish that is not a shark?
The beluga sturgeon, found in the Caspian and Black seas, is the largest known bony fish and can rival the ocean sunfish in size. The largest confirmed specimen was caught in the Volga estuary in 1827, measuring 7.3 meters (24 feet) and weighing 1,474 kilograms (3,250 pounds).
What is the 2 biggest fish?
The basking shark is the second biggest fish on the planet and, like the whale shark and blue whale, they feed by filtering tiny planktonic creatures from the water.
Is there a fish bigger than Megalodon?
Leedsichthys problematicus, which translates to “Alfred Leed’s troublesome fish,” was another massive sea creature from the prehistoric era. It was believed to be around 16.5 meters in length, which is larger than the average Megalodon. Despite its size, this fish was likely a filter-feeder rather than a predator.

Which fish can defeat shark?
Killer whales, which are actually a type of dolphin, are at the top of the food chain and feed on a variety of creatures such as fish, squid, seals, sea birds, and even whales larger than themselves, as reported by the Natural History Museum in London.
