All About Sharks

And I'm Doug Johnson.  On our program this week, we tell about sharks.  They are among the oldest animals on Earth.  Sharks are famous for attacking other sea creatures and even people.  Yet they also have been threatened by human activities.

The International Shark Attack File keeps records of all reported shark attacks.  The list has been in existence since nineteen fifty-eight.  The world attack totals last year were similar to those of the most recent years.  Yet the number of attacks has risen during the past century.  However, the number of deaths from shark attacks each year around the world remains very small. Experts say sharks killed only seven people last year.
