CHARLESTON, S.C. (AP) -- The U.S. Coast Guard says a boater has reported seeing three whale calves in one of the busier ship channels in South Carolina.
Coast Guard Chief Gary Herman says someone on a sailboat spotted the whales around 9 a.m. Monday in the Cooper River downstream from the Ravenel Bridge in Charleston.
The Coast Guard issued a bulletin on the sighting, but officials haven't confirmed the report.
Herman says the boater thought the calves were right whales.
Experts estimate there are just a few hundred of the North American variety of the 40-ton mammals left.
