Studying killer whales in the wild is expensive work. Transportation, equipment costs, boat maintenance and fuel are just some of the many daily costs faced by researchers in the field. By taking out a membership in the BC Wild Killer Whale Adoption Program, you’ll help defray these costs and become a key partner in the killer whale research effort.
