PENSACOLA BEACH, Fla. (AP) - A necropsy will be performed to

determine the cause of death for an oily young dolphin found

beached in a national park in the Florida Panhandle.

Wildlife officers tried to revive the marine mammal in shallow

waters after a family found it Wednesday in the sands in the Gulf

Islands National Seashore.

According to the U.S. Coast Guard and BP unified command center

in Mobile, Ala., the dolphin died as it was transported to a

rehabilitation center in Panama City. Authorities told the

Pensacola News Journal that the dolphin "had some oil on it" but

it wasn't clear why the animal beached itself.

A tourist from Arkansas said she and other beachgoers scraped

oil off the dolphin with their hands before wildlife officers

arrived. Christy Travis says they "had oil all over us."
