The list of animals injured and killed from the spill of the oil tanker Exxon Valdez includes sea otters, deer, eagles, owls and a host of other water fowl gathered up by rescue workers. Nearly 25 years after the Exxon Valdez oil spill off the coast of Alaska, some damage heals, some effects linger in Prince William Sound. (AP Photo/John Gaps III, File)
