The endangered Southern Resident orcas whistle and click their way around the waters of the Pacific Northwest in three small family groups while facing boat noise, pollution, and scarce food. Superpod introduces young readers to the experts who are training scat-sniffing dogs, inventing ways to treat sick orcas, quieting the waters, studying whales from the air, and speaking out. Author Nora Nickum also discusses her own work on laws to protect the orcas, tackles the dark history of orca capture for marine parks, and shares moments of wonder.
