4. Tiger Shark (3.11 tons, 24 feet)

The Tiger Shark, also known as Galeocerdo cuvier, is a large predatory shark found in tropical and subtropical waters around the world. It is named for its distinctive stripes on its body, which fade as the shark matures. Adult Tiger Sharks can weigh up to 3.11 tons and measure up to 24 feet in length, making them one of the largest predatory sharks in the ocean.

Tiger Sharks are known for their powerful jaws and sharp teeth, which allow them to eat a wide variety of prey, including turtles, sea birds, dolphins, and other sharks. They are also known to scavenge on carrion and are sometimes referred to as the “garbage cans of the sea”. Tiger Sharks are not picky eaters and have been known to consume non-food items such as license plates and rubber tires.

Despite their formidable size and reputation as aggressive predators, Tiger Sharks are not considered a major threat to humans. However, they are hunted for their meat, fins, and oil, and are considered near threatened by the IUCN. Conservation efforts are underway to protect these magnificent creatures and their habitats.

6. Ocean Sunfish (up to 10 feet)

The Ocean Sunfish (Mola mola) is the heaviest bony fish in the world, with adults weighing up to 5,000 pounds and reaching a length of 10 feet. They have a unique, flattened body shape, with a truncated tail fin and a distinct lack of a true caudal fin. Their skin is covered in a layer of mucus and rough texture, which helps protect them from parasites.

Ocean Sunfish are found in temperate and tropical waters worldwide, often near the surface in areas with strong currents. They are a favorite prey item for many marine mammals and sharks, and are known for their unusual swimming behavior, often drifting with the current and appearing to “sunbathe” near the surface.

Despite their large size, Ocean Sunfish feed primarily on jellyfish and other soft-bodied invertebrates, using their powerful jaws to crush and consume their prey. They are not typically targeted by commercial fisheries, but are occasionally caught as bycatch in gillnet and longline fisheries.

Ocean Sunfish are not considered endangered, but they are vulnerable to pollution and habitat degradation. Efforts to reduce plastic pollution and protect important habitats are important for the continued survival of this unique species.

7. Southern Sunfish (2.3 tons, 11 feet)

The Southern Sunfish, also known as the Mola mola, is the heaviest bony fish in the world. It is a unique-looking fish with a flattened, circular body shape that can reach a weight of up to 2.3 tons and a length of 11 feet. It has a grayish-brown color on the dorsal side and a white or silvery color on the ventral side.

Southern Sunfish are found in all the world’s oceans, but they are most commonly seen in tropical and temperate waters. They feed primarily on jellyfish, but they will also eat small fish, crustaceans, and squid. Due to their slow-moving nature, they are often preyed upon by sharks and orcas.

Southern Sunfish have a unique reproductive strategy. Females can produce up to 300 million eggs at once, which is the largest number of eggs produced by any vertebrate. They are also known for their ability to leap out of the water, sometimes up to 10 feet high, and for their sunbathing behavior where they float on their side near the surface of the water to regulate their body temperature.

Despite their large size, Southern Sunfish are not targeted by commercial fisheries due to their poor meat quality. However, they are often caught accidentally in fishing nets and can become entangled in marine debris.

What is the Biggest Fish in the World?

The largest fish in the world is the Whale Shark. This species can grow up to 70 feet long and weigh up to 47,000 pounds, which makes their size comparable to that of large whales. Sharks dominate the list of the largest fish, with the basking shark, great white shark, and tiger shark rounding out the top three.

The giant oceanic manta ray takes fifth place. Additionally, the largest bony fish is the ocean sunfish, which can grow up to 10 feet in body length and 14 feet in fin span and weigh over 5,000 pounds. The whale shark also holds the record for the largest living nonmammalian vertebrate on land, in the air, or in the water.

Although there are unconfirmed claims of individual whale sharks that are even larger and heavier, with lengths of up to 70 feet and weights of up to 75,000 pounds. To filter the tiny plankton that they feed on, whale sharks have very large mouths that can open up to almost 5 feet wide, with over 300 rows of teeth housing about 27,000 teeth.

Despite their name, whale sharks are actually sharks, which are cartilaginous fish. They are not aggressive man-eaters and are known to be gentle giants. In fact, snorkelers and scuba divers often seek them out to swim alongside them. However, the whale shark is listed as “vulnerable” on the International Union for Conservation of Nature Red List of Threatened Species due to threats from commercial fishing.

Whale sharks have a unique coloration pattern on their back and sides, with light spots and stripes over a dark gray, blue, or brown background. Scientists use these patterns to identify individual sharks, which helps them learn more about the species as a whole. The underside of a whale shark is light in color.
