David Attenborough Documentary coastal seas

90 percent of marine animals live coastal waters because sunlight reaches sea floors.
The documentary we watched was filmed in everglades national park in florida, USA.
The lush meadows of the park support the marine life.

- The Giant Trevally and stingray and extremely efficient good hunter.
Stingrays hunt for their prey that hide in the seagrass.
There is a lot of food for sea creatures, and for humans in 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 in the air making it easy for the dolphins to catch the mullet.


Coral reefs make up less than 1% of all marine species that live in the ocean. Coral reefs are missing an important member community - sharks.
-sharks numbers have been dramatically reduced due to overfishing.

Overfishing has reduced the shark population by 90%
