There are so many different types of fish in the world – some are shy and some are friendly, some are shy and some are aggressive. Plus, they are so colorful. In fact, think of a color and you are more likely to find a fish in that shade.
Also, you can find fish of different sizes. Some fish are very small, some are small and some are medium in size. Of course, there are also the ones that are big and then some are huge. Now we are about to share with you a list of 10 of those fish that are really huge, so huge that they are considered the largest fish in the world.
1. Whale Shark
A whale shark is the largest species of fish that exists today. They grow to almost 40 feet long and weigh around 20k pounds. These fish also have large mouths that are around 5 feet wide.
You can find them mainly in the tropical oceans of the world. Due to their white spot coloration, snorkelers and snorkelers easily identify them. Luckily for humans and also for the inhabitants of the sea, whale sharks love to eat plankton. Despite their enormous size, human beings really have no reason to be afraid of them.
2. Basking Shark
The second-largest living fish in the world is the basking shark. An adult basking shark can grow almost 26 feet long. They generally have mottled skin with a brownish color.
You can find these fish in the temperate oceans of the world. They are slow to move and never go into hibernation. Basking sharks usually spin on their own in the ocean and the main food they love to eat is zooplankton. Like whale sharks, basking sharks pose no danger to humans either.
3. Tiger Shark
The tiger shark is another large species of fish that lives today. It can grow up to 16 feet long and weigh almost 3 tons. This species is commonly found in temperate and tropical oceans. Younger sharks have black tiger-like stripes on their bodies and this fades with age. It is from these stripes that this species gets its name.
These sharks enjoy eating aquatic creatures, garbage, and also sea birds. Tiger sharks are known to attack humans as well.
4. Manta Ray
Manta Ray is also one of the largest fish in the world and grows up to 23 feet long. It is the large saw on the head of these fish that contributes to their enormous size.
You can find this species in subtropical and tropical waters, and also in warm and temperate waters. This fish is quite popular with divers and the food they like to eat is mostly plankton.
5. Great White Shark
The great white shark is not only one of the largest fish, but also the most popular shark in the world. Females can reach almost 20 feet in length and can swim at speeds of up to 35 miles/hour.
These fish are the largest predators in the world and are found in the coastal surface waters of all major oceans. Although humans are not typically their prey, there have been unproven news of their attacks on humans.
6. Ocean Sunfish
Also known as “mole”, Ocean Sunfish is another giant fish. They can grow up to 11 feet long and weigh almost 2.5 tons. This fish has a unique appearance. They do not have a true tail and, in fact, it appears that it has been cut in half.
Ocean Sunfish loves to eat parasites. You may often see them near the ocean’s surface basking in the sun, and in fact, this is why they are called the Ocean Sunfish.
7. Marlin

The females are quite a bit larger than the males and can reach almost 14 feet in length and weigh about 1,985 pounds.

9. Halibut
