  On a particularly unusual event, when there was a shark watching crowd at the island, about 14 or so of them came into Moraga Bay at the SouthEast Farallons and went from boat to boat, then breeching in the surf at the point, circling back by every boat and leaving the area in the same fashion. A white shark even breeched to observe this. Many naturalists present can confirm this event.

  The bottlenose dolphin is perhaps one of the most well known cetaceans, because of its widespread use in marine parks and research facilities. The bottlenose dolphin may be best known as "Flipper" (as seen in the television series). This is the dolphin most frequently seen along the shores of the United States. This species is very flexible in its behavior.

• Harbor Porpoise
  Harbor Porpoise information at ASConline.org Cetacean Society Fact Sheet.
  One of the smallest of the oceanic cetaceans, the harbor porpoise is shy and elusive, not inclined to approach boats and bow ride, as many other species of dolphins and porpoises do. On calm days these animals can be easily detected by the loud puffing sound they make as they surface to breathe. Because of its inshore habitat, it is one of the best-studied small cetaceans, and also one of the most frequently hunted.
  One of our boat captains refers to them as "chocolate chips" when sited. They are next to impossible to photograph. Sandra, sfbaywhalewatching.com previous owner and founder, refers to them as rockstars of the sea. Live fast, die young.
