A Killer Whale tail slapping which is seen occasionally off Northern Vancouver Island in British Columbia. This type of behaviour often occurs when the whales are in close contact with their pod or grouped together with other pods and which seems to be a form of communication. Whether tail slapping is a friendly or an aggressive form of behavior is not proved beyond a doubt but a majority of the times it seems to be playful. The sound that echoes after a tail slap can be very loud especially when the water is calm and there is nobody else in the same vicinity except for the boat that you are on. Again “spectacular” is the word and the reason for the behaviour is less important.
Just realized that the photo in this post ties back to the post on July 10 with the mother and cub each sitting on their own rock. This photo could be indicate the cub was complaining and mother came to check or to console because no salmon have arrive for lunch.
