Orcinus orca
The killer whale is the largest member of the dolphin family and one of the most powerful predators on Earth. BC waters are home to three distinct populations: Northern Residents, Southern Residents, and Transients (Bigg's). The Southern Resident population is endangered, with only around 75 individuals remaining. These iconic black and white cetaceans are highly intelligent and live in complex matrilineal social groups.
