A shark that was captured in shallow waters where it had become a daily lure for tourists on a beach died Wednesday at the Barcelona Aquarium.

Biologists had said they did not expect the 7-foot female sandbar shark to survive because it stopped swimming after being brought to the aquarium Monday and needed help from divers to keep moving and thus breathing.

An autopsy will be carried out to determine the cause of death, the aquarium said. Preliminary test results showed the shark had died due to a 2 1/2-inch hook caught in its esophagus.

Biologists captured the 200-pound shark Monday in knee-deep water at a beach called Miracle in northeast Tarragona province. The shark first turned up early last week and became a novelty by swimming regularly into plain view in very shallow waters. Authorities closed the beach to swimmers.
