I don"t know the differance in seals .a seal is a seal and some are big .Dyke rd comox courtenay flood tide .veiw seals in there playground .20 or more at one time .they realy like the boundery marker off the air strip .Seals hang around the fishers on shore in Royston , as the seals has put the salmon in front of you and have the fisher do the work for the seals meal.I went rowing in the comox bay and had 5 seals following the boat for 4 hours,I gave up ,no reward and came to shore.Almost need decoy fishermen petending to have fish on ,to let the fisher have a chance at a few fish passing by.
