If a whale encounters a period of low prey abundance, it will mobilize energy in its fat reserves, thus releasing those pollutants into its blood stream, which can degrade the whale’s health, affect its reproductive potential and even lead to death. When the first population census was conducted in 1973, 66 whales were sighted.Their population increased by 48% to a high of 98 in 1995, then dropped 16% to 82 individuals between 1995 and 2003, prompting governments to list them as endangered species.As of December 2016, there were 78 Southern Resident Killer Whales in the Salish Sea.Click graphic for a larger image.
