(Seaside, OR) -- Authorities are confirming an olive ridley sea turtle was found dead last week on Sunset Beach near Fort Stevens State Park. The Seaside Aquarium says the 40 pound turtle was likely blown into the cold waters off the Oregon Coast by recent storms. Most sea turtles that are found on Oregon beaches die. It can be difficult to determine if they're alive, because they're cold and their heartbeat is so slow it's tough to detect. If they do survive and aquariums help them recover, they can be released into the wild.
