Surface behaviors of Southern Resident Killer Whales, Orcinus orca, along the West Side Scenic Preserve of San Juan Island
Southern Resident Killer Whales have been studied since their population was harmed by live captures for aquariums and has not recovered since that time. Further understanding of their behavior could assist conservation efforts. Killer whales spend the majority of their time underwater, so surface b...
