(Newport, OR) -- A green sea turtle that was found on Manzanita beach over the weekend has died. Turtles normally swim in warm water, and when they get caught in currents that bring them along the Oregon and Washington coasts, they suffer hypothermia. Staff from the Seaside Aquarium rescued the turtle and took it to the Oregon Coast Aquarium in Newport, which is certified to treat turtles. After two days of round-the-clock care, the turtle died. Most turtles that are found on Oregon beaches don't survive their injuries. A necropsy will be performed to determine why the turtle died.
