(Astoria, OR) -- The National Oceanic and Atmospheric Administration is investigating the death of a 40-foot sperm whale that washed ashore at Fort Stevens State Park. Officials with the Seaside Aquarium say the whale appears to be a juvenile male and was likely dead for some time before it washed ashore. The whale has some large gashes on its body that officials believe came from a collision with a ship. The aquarium has removed the whale's lower jaw for scientific purposes and says officials will perform a necropsy sometime later this week.
