GoPro captures extreme footage of salmon spawn

Salmon in Lake Ontario make a remarkable journey every year to find the spot that they were born. It is here that the females will deposit eggs and the males will fertilize them. The Ganaraska River is a shallow tributary that runs into Lake Ontario and it is one of many rivers that are crowded with spawning salmon every August. Salmon have an incredible sense of smell and it is believed that their remarkable journey is guided by the memory of the scent of their birthplace. They are driven by an urge so powerful that for many, the August run will be their final act, as they expire within a week of completing their journey. In preparation for the migration, salmon change colors and stop eating. One of the most amazing changes is that the males will experience the growth of large canine teeth and hooked jaws, which aid in the battle for breeding rights.
