Thirty years ago, when
the movie version of my novel Jaw was published, few people including me knew
very much about great white sharks. For hundreds of generations, we humans have
been taught to fear and hate sharks, and the movie touched
nerve of horror.
Now something long
thought impossible has happened.great white shark was successfully held in
capacity for several months. In August last yearvery young female great white shark was
caught accidentally infisherman's net off Huntington Beach,
California, and then kept in an ocean pen (栏栅)
for 25 days. After being moved to the Monterey Bay Aquarium (水族馆),
she grew well in the million-gallon Outer Bay Exhibit. She was so lovely that
people all liked her very much. Perhaps she was too young to understand that
the big tank was not her natural environment, because she didn't hit her head
against the walls in an attempt to swim away as others of her kind have done.
And she began to feed almost immediately on small fish offered to her onpole. In the months that followed, the shark
suffered no serious injuries, caught no diseases, and grew noticeably larger,
breaking all records for great white sharks in capacity. The longest that any
other great white shark had been held was 16 days.
Until February 23, that
is, when she hit and killed
soup fin shark (翅鲨)
, as she grew bigger and her behavior grew more aggressive, officials at the
Aquarium knew the time had come. On March 31, after 198 days in the aquarium,
the great white shark was released into the Pacific.
Scientists still havelot to learn about sharks, especially great
white sharks which are now considered to be in danger. Scientists do know that
sharks are necessary to ocean health. Remove any significant animal from the
sea food chain and you will risk destroying the balance of nature.
