Sharks have an amazing sense of smell.
Sharks have a very keen sense of hearing but even more amazing is the fact about the sharks is that they can smell one drop of blood in a million drops of water!
Seems like fantastic but some sort of shark can certainly identify a fish’s heartbeat nearly 85 cm away.
Did you know?
- A great light shark doggie begins looking for food when it is born!
- A shark can live up to 6 weeks without eating!
- Did you know that sharks have only changed very little over the last 400 million years!
- That means they were around 200 million years before the dinosaurs and that they look nearly the same now as they did when dinosaurs roamed the land.
- There are over 350 different kinds of sharks and they live all over the world’s oceans. Some even live in rivers.
- Sharks come in all kinds of shapes and sizes. Their size can range from about as big as your hand to larger than a school bus.
- Sharks are fish but they are quite different. Most fish have bones in their bodies but sharks don’t have a single bone. Their skeleton is made out of cartilage, which is a material that bends much more easily than bone.
- If a shark would stop swimming it would sink like a stone. That’s why they always cruise around the water.
- A shark does not chew – it swallows its food in whole.
- A shark can grow a whole mouthful of teeth in one week.
