Dolphins and whales were once again spotted on Saturday's cruise. A large group of Risso's dolphins and a large pod of bottlenose dolphins were viewed as the boat traveled to Los Coronados Islands. They gave everyone a good show; some of the dolphins breaching. On the return trip, a spout was seen. Whalers Heather and Diane consulted their books, and could not identify the whale from the pictures. After much discussion they decided it could have been a pygmy sperm whale since its head seemed rounded like this type of whale. All could agree it was a "mystery." It was another great day on the water on board the Nature Cruise.
