1. Megalodon (Carcharocles megalodon)

The largest shark to ever roam the oceans was the prehistoric Megalodon. This extinct species is estimated to have reached lengths of up to 60 feet (18 meters), making it the biggest shark in history. Fossil evidence shows it had a bite powerful enough to crush whale bones.
2. Whale Shark (Rhincodon typus)

The modern-day whale shark is the largest living shark, with the biggest recorded specimen measuring 61.7 feet (18.8 meters). Despite their enormous size, whale sharks are gentle giants that feed primarily on plankton.
3. Basking Shark (Cetorhinus maximus)
The second-largest living shark is the basking shark, which can grow up to 40 feet (12 meters). Like whale sharks, they are filter feeders, harmlessly consuming plankton as they swim with their mouths wide open.
4. Great White Shark (Carcharodon carcharias)
The largest predatory shark in modern oceans, the great white, can reach lengths of up to 20 feet (6 meters). The biggest recorded great white, known as “Deep Blue,” was estimated to be 20 feet (6.1 meters) long and over 5,000 pounds.
5. Tiger Shark (Galeocerdo cuvier)
Tiger sharks are known for their massive size and powerful build. The largest recorded tiger shark reached 18 feet (5.5 meters). They eat a wide range of prey, including sea turtles and even garbage.
6. Greenland Shark (Somniosus microcephalus)
One of the longest-living vertebrates on Earth, Greenland sharks can live for centuries and grow up to 24 feet (7.3 meters). While they are not the fastest swimmers, their immense size and longevity are awe-inspiring.
7. Thresher Shark (Alopias vulpinus)
Known for their distinctive long tail, thresher sharks can grow up to 20 feet (6 meters) in length, nearly half of that length coming from their whip-like tail. They use their tail to stun prey before devouring it.
8. Goblin Shark (Mitsukurina owstoni)
The goblin shark is a rare deep-sea species known for its unusual appearance, with a long, flat snout and protrusible jaws. While not as massive as some other sharks, it can still grow up to 13 feet (4 meters) in length. Due to its ancient lineage, these sharks are often considered “living fossils.”
9. Hammerhead Shark (Sphyrna mokarran)
The great hammerhead is the largest species of hammerhead shark, reaching up to 20 feet (6 meters) in length. Its wide, flat heads enhance its sensory capabilities for detecting prey.
10. Bluntnose Sixgill Shark (Hexanchus griseus)
This ancient deep-water shark species can grow up to 20 feet (6 meters) long. With their prehistoric appearance and six-gill slits (most sharks have five), they are one of the largest and most primitive sharks still alive today.
11. Megamouth Shark (Megachasma pelagios)

Discovered only in 1976, the megamouth shark can grow up to 18 feet (5.5 meters) long. Despite their size, they are filter feeders like the whale and basking sharks, swimming slowly through the ocean to catch plankton.
12. Mako Shark (Isurus oxyrinchus)
The shortfin mako shark is the fastest shark in the ocean, reaching speeds up to 45 mph (72 km/h). It can also grow to impressive sizes. The largest recorded mako was over 13 feet (4 meters) long.
13. Bull Shark (Carcharhinus leucas)
Although typically smaller than other sharks on this list, bull sharks can grow up to 13 feet (4 meters) in length and are known for their ability to thrive in both saltwater and freshwater environments. They are considered one of the most dangerous sharks due to their aggressive nature and frequent contact with humans.
