English: This white killer whale (Orcinus orca) was spotted with its pod about two miles off Kanaga Volcano, part of Alaska’s Aleutian Islands, on February 23, 2008. At the time, Kodiak-based Oscar Dyson was on a research expedition for the National Oceanic and Atmospheric Administration's Alaska Fisheries Science Center, assessing pollock fish stocks near Steller sea lion haulout sites. This white whale is a fish-eating type of killer whale, as were all the killer whales photographed on the expedition. Fish-eating killer whales are the most frequently seen whales around the Aleutian Islands during the summer. The winter sightings represent important evidence that they may be common year-round.
