Workers in boats struggled Wednesday to coax nearly four dozen pilot whales out of dangerous shallow waters in Florida's Everglades National Park, hoping to spare them the fate of 10 others that have died.

Six were found dead, and four had to be euthanized Wednesday, said Blair Mase, of the National Oceanic and Atmospheric Administration.

The whales are in a remote area about 20 miles east of where they normally live. It takes more than an hour to reach the spot from the nearest boat ramp, and there is no cellphone service.

Mase said she did not know why they had beached, but the species is known for its close-knit social groups, meaning if one whale gets stuck or stays behind, the others are likely to stay behind, too. - AP
