FILE- This Wednesday, June 17, 2009 file photo shows the tide as it slowly comes in over a horseshoe crab seen at Thomas Point Beach in Brunswick, Maine. The horseshoe crab can be found on the Atlantic coast from Maine to the Yucatan, with the largest population in the Delaware Bay. The horseshoe crab is more closely related to scorpions and spiders than crabs, according to marine biologists at the Georgia Aquarium in Atlanta. (AP Photo/Pat Wellenbach, FILE) less
