Facts You Should Know About Sharks #facts #animals #sharks

Glow-in-the-Dark Sharks

Some sharks, like the swell shark and chain catshark, can actually glow in the dark!

This is due to a phenomenon called bio-luminescence.

No Bones About It

Sharks don't have bones! Instead, they have cartilage (the flexible stuff in your nose and ears) which makes up their entire skeleton.

Tooth Conveyor Belt

Sharks continuously lose and regrow their teeth throughout their life. Some species can go through over 30,000 teeth in their lifetime!

Ancient Giants

The megalodon, a prehistoric shark, was so big that an adult human could stand inside its open mouth. It's one of the largest predators ever to exist weighing the same as 30 Great White Sharks!

The Lazy Shark

The nurse shark is known to be quite lethargic. It often just lies on the ocean floor and doesn't move much, unlike the stereotype of the always-moving shark.

Sensitive Noses

Sharks have an incredibly keen sense of smell. They can detect blood in the water from miles away, and in some cases, they can sense as little as one part of blood in 100 million parts of water.

Electro-Sensors

Apart from their strong sense of smell, sharks also have special sensors called the ampullae of Lorenzini. These sensors detect electrical fields emitted by other animals, helping sharks locate prey.

Diverse Diets

While some sharks eat fish or seals, others have a taste for unusual items. The tiger shark, for instance, has been known to eat license plates, tires, and other debris.

Sharks in Cold Waters

The Greenland shark lives in Arctic and sub-Arctic waters and can live for up to 400 years, making it one of the oldest living vertebrates on the planet. 

No Sleepy Shark

Sharks don't sleep like humans do. Instead, they have periods of rest and activity. Some species have to keep moving to breathe, while others can rest on the ocean floor.
