B
     Sharks frighten most of us, but Daniel Weaver, a shark scientist, swims with them for a living! We asked him some questions about this unusual job.
     So Daniel, what’s it like to be a shark scientist?
     Well, it’s a great job. I often travel to faraway places like South Africa and Fiji to study sharks. On the other hand, a shark scientist sometimes does boring desk work, such as writing reports. Also, shark scientists don’t usually get paid a lot.
     What qualities (品质) do you need to become a shark scientist?
     Shark scientists need to be wise and strong. They enjoy working outdoors and they have to be cool and patient (耐心). They also have to be quite brave!
     So do you think it’s a dangerous job?
     Well, sharks have up to 15 rows of sharp teeth. However, sharks hardly attack (攻击) humans. There are over 350 kinds of sharks in the world and only about 10 are dangerous to us. In fact, dogs kill more people every year than sharks! Humans kill over 12 million sharks a year for food and sport!
     How do you become a shark scientist?
     A shark scientist usually studies Marine Science or Zoology at university. It’s also good to get some work experience in an aquarium (水族馆). In my opinion, I have the best job in the world!
