David Attenborough Documentary Coastal seas

Today we watched the our Planet Documentary, narrated by David Attenborough,called Coastal Seas.Here are some interesting facts we learnt:

• 90 percent of marine creatures live in coastal waters.This is because the seafloor is in reach of sunlight.
• The documentary we watched was filmed in the Everglades National Park,Florida USA.
• The lush meadows of the park support the marine life.
• The giant Trevally and Sting Ray are extremely good hunters.
• Stingrays hunt for their prey that hide in the seagrass.
• There is a lot of food for the sea creatures,and for the humans in the coastal waters.
• The bottlenose dolphin has a special way of hunting shoals of mullet.They create a circle around the fish and flick up the mud which makes the water murky-the mullet then get confused and jump up in the air,making it easy for the dolphins to catch the mullet.
• Coral reefs make up less than 1% of all the marine species that live in the ocean.
• Coral reefs are missing an important member of the community -Sharks!
• Shark numbers have been dramatically reduced due to overfishing 
• Overfishing has reduced the shark population 90%
