Dall’s porpoises are by far the most frequently seen marine mammal on our tours. They tend to be seen very frequently around the Blinkhorn Peninsula area, easily attainable on our half day tours.
Description: Dall’s porpoise, named after the American naturalist H.W. Dall, resembles the Orca but is much smaller, averaging 1.8 metres (6 feet) long and weighing in at about 180 kg (400 lbs). They are easily recognized by their white-tipped dorsal fin. They live in the Pacific Ocean ranging from Baja California to Alaska, the Bearing Strait and off the coast of Japan.
What they eat: They eat small fish such as herring and cephalopods
Predators: Transient killer whales, sharks, humans. Thousands are killed by Japanese whalers every year; the moratorium imposed in the mid -1980’s on the whaling industry caused a decrease in their numbers as they are used as compensation to whale meat.
Lifespan: Normal life span is 15 years.
They are fast swimmers and can easily reach speeds over 25 knots or 30 mph; they love to bow ride and can often be seen “rooster-tailing” a technique that creates pockets of air allowing them to breathe while swimming.
