Pacific white-sided dolphins, known for the distinct coloring that give them their name, are a playful and highly social marine mammal. They are also sometimes known as the “hookfin porpoise” because of their large, curved dorsal fin, though they are not technically porpoises. In the United States, Pacific white-sided dolphins live off the coasts of California, Oregon, Washington, and Alaska. They can be seen traveling in schools of thousands, but group sizes are usually between 10 and 100 animals. These dolphins are often seen “bow riding” (swimming near the front part of a ship) and jumping, somersaulting, or even spinning in the air. Pacific white-sided dolphins in the United States are not endangered or threatened, but they are protected under the Marine Mammal Protection Act. A primary threat to Pacific white-sided dolphins is entanglement in fishing gear, such as gillnets and trawls. NOAA Fisheries is dedicated to the conservation and protection of Pacific white-sided dolphins. We are working to help conserve this species through collaborative management, integrated science, partnerships, and outreach.
