It's time to go to the deep and dark parts of the OCEAN!
Here we come Sharks! Lets see how the sharks live in the ocean.
There are more than 465 known species of sharks living in our oceans today. Sharks are an apex predator at or near the top of their marine food chains, and they regulate the populations of species below them. Research has shown that massive depletion of sharks has cascading effects throughout the ocean’s ecosystems.
Sharks are fish. But how is a shark different from other kinds of fish?
- Most other fish have skeletons made of bone. A shark's skeleton is made of cartilage, a type of strong but flexible tissue.
- Most other fish are covered in smooth, flat scales. A shark is covered in sharp, toothlike scales called denticles.
- Most other fish have just one gill slit—an organ for breathing—on each side of the body. A shark has five, six, or even seven gill slits on each side.
- Most other fish have flaps over their gills. Sharks do not.
Ancient Sharks lived before land vertebrates populated earth and even before than many plants developed on continents. While they were very different from those found today, sharks have been on this planet for long time.
The shark species as we know them have been around for 100 million years. This means that they were here when dinosaurs were around. A record breaking evolutionary creature cannot be anything but amazing, with an anatomy which has been improved over those million years of evolution.
