英语听力：自然百科 海洋天堂大堡礁:堡礁内外—18

 This is a known mindless killer¹. The shark is smart. It pitches up at the peak of the turtle nesting season, and simply waits for the tide to deliver its food.-Ah, look at that so distinctive²...have the boat. Tigers are a big fan with all manner interesting things in their stomaches, and as an opportunist predator³, she's coming in and just have a little look at the boat and a little look at me. Just snatching the boat, she's using the nose and all the senses packed into the nose to figure out what we are, what I am. And now she's heading back to the calves⁴, I hope. Watch his bite! It's grip. What she's doing now is sawing, using the weight of the body, she's huge havoc⁵ animals. And you get a lot of torture without wait, and with that torture, you clehch jaws⁶ onto the flipper⁷ or the head and just rip from side to side, and by that mechanical action and the cutting action at the teeth will tear the flesh off.

Viberations from the commotion⁸ and the older of the marsh⁹ turtle flesh are carried on the currents, attracting more sharks to the feast. But this is no feeding frenzy¹⁰. Sharks of this size can do each other real damage, so instead they take it in turns, with smaller sharks defering to the larger ones.
