A five-week-old orphaned Southern Sea Otter pup rests on a rubber mat after arriving at the Shedd Aquarium's Abbott Oceanarium in Chicago, Oct. 28, 2014. The stranded pup was found on September 30th at Coastways Beach in California and was rescued the next day to be brought back to health at the Monterey Bay Aquarium. Southern sea otters were listed as "threatened" under the U.S. Endangered Species Act in 1977.
