The Salmon Specialists
Detailed Description
Orcas (Orcinus orca) of the AD8 pod search for schools of salmon in Amalik Bay. Orca populations have declined significantly since the Exxon Valdez oil spill in 1989. By collecting photos of saddle patches and dorsal fin notches, scientists are able to identify unique individual whales. Photo IDs provide vital information on the exact ages of individuals, calving rates, survival rates, and the overall health of the population.
