Amazing Shark Facts
Ancient Survivors
Sharks have been swimming in our oceans for over 400 million years, predating dinosaurs by nearly 200 million years. They’ve survived multiple mass extinction events.
Electrical Sense
Sharks can detect electrical fields as weak as 5 billionths of a volt through special organs called ampullae of Lorenzini, helping them locate prey.
Speed Demons
The shortfin mako shark can reach speeds of up to 60 mph (97 km/h), making it one of the fastest fish in the ocean.
Tooth Factory
A single shark can produce over 40,000 teeth in its lifetime. They continuously shed and replace their teeth throughout their lives.
Super Vision
Sharks can see in color and have excellent night vision. Some species can see 10 times better than humans in low light conditions.
Size Extremes
The whale shark is the largest fish in the world at up to 40 feet long, while the dwarf lanternshark is only about 8 inches long.
Shark Species
Meet 22 different shark species from around the world. From the massive whale shark to the fearsome great white, discover the incredible diversity of these ocean predators.
Blue Sharks
Blue sharks are sleek, migratory predators that primarily feed on squid and small fish and are often found in temperate and tropical waters around the world.
Tiger Sharks
Tiger sharks are large, powerful predators recognizable by their dark vertical stripes and reputation as opportunistic feeders that consume a wide variety of prey.
Scalloped Hammerhead Sharks
Scalloped hammerhead sharks are easily identified by their distinctive, scallop-shaped head and are known to form large, graceful schools in warm coastal waters.
Wobbegong Sharks
Wobbegong sharks are bottom-dwelling ambush predators with ornate, carpet-like patterns that help them blend seamlessly into the seafloor.
Caribbean Reef Sharks
Caribbean reef sharks are agile, medium-sized predators commonly found near coral reefs, where they play a vital role in maintaining the balance of the marine ecosystem.
Great White Sharks
Meet the ocean’s most famous predator. Learn about the great white’s hunting strategies, size, and role as an apex predator.
Bull Sharks
Bull sharks are aggressive, adaptable predators known for their ability to thrive in both saltwater and freshwater environments, often swimming far up rivers.
Gray Reef Sharks
Gray reef sharks are swift, social hunters often seen patrolling coral reefs in groups, known for their distinctive threat display when feeling challenged.
Greenland Sharks
Greenland sharks are slow-moving deep-sea giants that can live for centuries, making them one of the longest-living vertebrates on Earth.
Whale Sharks
Whale sharks are gentle filter feeders and the largest fish in the ocean, gliding gracefully through warm waters while consuming plankton and small fish.
Lemon Sharks
Lemon sharks are social coastal predators recognizable by their yellow-brown coloring, often found schooling in warm, shallow waters.
Sand Tiger Sharks
Sand tiger sharks are fierce-looking but relatively docile predators that often hover motionless near reefs and wrecks, using their sharp, protruding teeth to grasp slippery prey.
Thresher Sharks
Thresher sharks are easily recognized by their extraordinarily long, whip-like tails, which they use to stun schools of fish before feeding.
Basking Sharks
Basking sharks are massive, slow-moving filter feeders that cruise near the ocean surface with their mouths wide open to strain plankton from the water.
Megalodon Sharks
The megalodon shark was an enormous prehistoric predator, believed to be the largest shark to ever live, with jaws powerful enough to crush whales.
Spiny Dogfish Sharks
Spiny dogfish sharks are small, schooling sharks distinguished by the sharp spines in front of their dorsal fins and their remarkable endurance during long migrations.
Whitetip Reef Sharks
Whitetip reef sharks are slender, nocturnal hunters that rest in caves by day and prowl coral reefs at night, easily identified by the white tips on their fins.
Oceanic Whitetip Sharks
Oceanic whitetip sharks are bold, slow-cruising predators that inhabit open oceans and are easily recognized by the rounded white tips on their large fins.
Great Hammerhead Sharks
Great hammerhead sharks are solitary, powerful predators distinguished by their wide, T-shaped heads and tall dorsal fins, often found patrolling warm coastal waters.
Nurse Sharks
