Lynn Morris from the UK provides these photos showing a humpback whale diving and showing the underside of it’s tail. The unique pattern on the tail is used to identify individual whales the same as the dorsal fin and saddle patch is used to identify the orca. The lodge’s whale watching safari area of Bold Head in Blackfish Sound normally contains eight or ten humpback whales, which feed on the herring in the area. The same herring attract the salmon, which in turn are the main attraction for the orca. It is not uncommon to be watching orca and whales at the same time, remembering these are the resident or salmon eating orca.
