Shark Adaptations

Sharks are apex predators, meaning they're at the top of their food chain, hunted only by humans. Other apex predators include lions, bald eagles, and crocodiles.

Swimming Abilities

Sharks' bodies and fins are specially shaped for speed and efficiency in water.
Their caudal fin (tail) is V-shaped, with the top section larger than the bottom, boosting swimming efficiency.
Sharks have skeletons made of cartilage, not bone, which is lightweight and allows for quick movement.
Sharks need to move constantly to breathe, absorbing oxygen from the water through their gills. They usually have more gills (five to seven) than other fish.

Sensing Electricity

Sharks possess a sixth sense—they can detect the electricity produced by living things via specialized organs called ampullae of Lorenzini. This helps them find and hunt prey.
Sharks have an extraordinary sense of smell, allowing the Great White Shark to detect blood in the water from considerable distances.

Jaws and Teeth

Sharks' teeth are embedded in their gums and are continuously replaced throughout their lifespan.
They grow in rows and sharks lose thousands of teeth over their lifetime.
Tooth shapes vary depending on the shark species, from sharp, ripping teeth to flat, crushing teeth.

Camouflage

Sharks' coloration typically features darker backs and lighter bellies (countershading).
This countershading helps them blend into their environment, allowing for stealthy hunting.
