These small chunky cetaceans have black and white markings that give them the appearance of a mini Killer Whale / Orca. There have been reports by people mistaking Dall’s porpoises for baby Orca, but the lack of white eye patches and a much smaller dorsal fin is definitely a Dall’s.
Dall’s Porpoise travel in small groups of two to eight animals rarely in larger groups of around twenty-five. They zip about quickly in random back and forth patterns looking for food. As they speed through the water, they throw a rooster tail type of splash. This is quite distinctive as they shoot along just below the surface of the ocean. They are known to travel at around 30 knots (56 kph or 35 mph). With all this speed it can be a challenge getting good photos. For this reason we often stop and they will make passes by the boat and sometimes we get lucky. They are very playful and are at times known to harass humpback whales see tomorrows post…..
