Dall’s porpoises are speed demons reaching speeds up to 55 km/hr. They suddenly appear out of nowhere and disappear the same way. Although they ride in both bow and stern wakes of boats, they seldom stay for very long. Next to impossible to get a photo if you are moving but frequently if the boat stops suddenly while they are playing they will come to investigate and it is possible to get “under water” photos. The white in the corner of the photo is the edge of our boat.
