英语听力：自然百科 大堡礁：自然奇迹—4

 Even though, coral reefs cover less than 1% of world's oceans. They contain a quarter of all known marine¹ life. And the Great Barrier Reef is the biggest of them all. 

 

“I still vividly² remember my first dive on a coral reef over 20 years ago. And the moment I put my head in the water, I knew what I wanted to do for the rest of my life. ”

 

Even if I spent my entire life underwater, I still couldn't hope to see all the species that live on this reef. 

 

“400 species of hard coral, 300 of soft coral, 1,600 species of fish, 134 species of shark and ray, 30 species of whale and dolphin, 6 species of turtle, 14 species of sea snake, 3,000 species of mollusc..."

 

The sheer number of creatures that live here makes the reef as hectic³ as any human city. With a rhythm of almost perpetual rush hours.
