Transcript of SHARKS

Sharks structural adaptations are that they have gills, fins and a streamline bodies to help them swim. Sharks also have teeth that grow right back in after they lose one. That is how a shark lives so well in the ocean.
Sharks behavioral adaptations are that they are bigger then any other fish in the water and they can fit their prey in their mouth. Sharks most of the time go to catch a prey at night or sunrise so that they won't be seen.

Sharks live in salt water so they are mostly found in oceans but some types of sharks live in fresh water too. Sharks will also follow a trail of food when they need to, so they can travel hundreds and hundreds of kilometres to find the food they need in order to survive.

Sharks eat meat, they feed on fish, small sharks, sea lion and even dolphins. Sharks can smell and see very well. Sharks can hear a dolphin coming from hundreds of kilometres away. Sharks can smell a school of fish coming from hundreds and even thousands of kilometres away.
A shark doesn't really have a predator because it is at the top of the water food chain. The one thing that can eat a shark is a bigger shark because it is larger and it can fit it in it's mouth.
A shark is a fish because it has gills. A shark is different from a whale because whales breath air and sharks breath water.
