Until my recent visit to the Sooke Potholes I didn't know that we had crayfish in this area. I always thought they were only to be found in the southern USA. These were caught to show to some young children and I happened to be nearby. Although they are edible they were released shortly after this photo was taken. Crayfish are apparently very sensitive to pollution so it was nice to see them in the Sooke River, which is fed by a reservoir that provides Victoria's tap water. These crayfish were about the size of a little finger. I think they are probably Signal Crayfish (Pacifastacus leniusculus).
