SHARKS

梁尚贤 Alex

Hi， everybody， This is the sharks science report.

Sharks are built up with three parts--head， body and tail. The highest speed of the great white sharks can up to 69 KM per hour. The lowest speed of the lantern sharks can be 1.22 KM per hour. In the world， nearly 60% of the sharks are being eaten by people and polar bears. The sharks only live in the sunlight zone and the twilight zone. They don’t live in the midnight zone because the midnight zone is very dark and there is not much food for the big sharks there. Their main food is swordfish and salmon. They even don’t close their eyes while sleeping！ It is very special.

I love animals and I would like to share my love to protect them.
