Hundreds of dolphins passed within five kilometers of the Netanya and Givat Olga shores yesterday, in what Israeli maritime experts call a most unusual phenomenon. Staffers at the Israel Center for Research of Water Mammals say that the school spread our over a 1.5-kilometer-wide area, and was of undetermined length. Only a few dozen of the hundreds of dolphins were photographed, as the researchers did not want to disrupt the school\'s path.
