Some 15 dolphins, including mothers and calves, gave an acrobatic display off the Israeli coast near Haifa. They performed for over an hour to a team of Haifa University marine scientists conducting an exploration project, 10 miles from the shore. It was the most exciting display ever seen by the scientists.
