Frances Gulland, a veterinarian with the Marine Mammal Center, answers questions about the condition of two humpback whales that swam about 90 miles up the Sacramento River to the Port of Sacramento, May 16, 2007. The pair, believed to be a mother and her calf, made their way into the area on May 15. Both whales have wounds that marine experts believe were caused by a ship's propeller.
