The discovery of a skipjack tuna (Katsuwonus pelamis), primarily a fish of warm tropical waters, off Copper River, in Alaska, 200 miles north of the previous geographic limit, and a dead sooty storm-petrel (Oceanodroma tristrami), a species native to Northern Asia and Hawaii, along with a few brown boobies (Sula leucogaster) in the Farallon Islands of California, besides other such records, has led to worries amongst marine biologists that the food web across the Pacific is in danger of disruption.
