HILTON HEAD ISLAND, S.C. (AP) _ A woman swimming off this resort island was bitten from her chest to her thigh by what authorities suspect was a 10- to 12-foot shark.

Lioubov Kozarinova of Gaithersburg, Md., was in good condition Monday.

''She should be OK,'' friend Alex Grinberg said from Kozarinova's hospital room. ''The pain is not too bad now. She's been given painkillers. She told me that it was a shark that attacked her, but she didn't know what kind.''

Kozarinova had been swimming Sunday about 50 to 75 yards offshore. Whatever bit her had a bite radius of 18 inches, said fire Battalion Chief Eddie Johnson.

It was probably 10 to 12 feet long, and may have been drawn into the area by a nearby shrimp boat, he said.

''It was typical of a shark attack. She was bitten, then it pulled away and let go, which is what sharks usually do,'' Johnson said.

The last serious shark attack here was in 1988, when a man was bitten as he swam in waist-deep water.
