killer whale

A killer whale more than 20 feet long died after beaching itself in Palm Coast, Fla. This is the third known orca to be stranded in the southeastern U.S. and the first since 1956, an official says.

A killer whale attempting to say "hello" or "Amy" did not sound as clear as, say, a parrot. But scientists found that the whales could repeat human vocalizations with some success.
