Fishermen arrive on shore in the fishing village of Popotla, Mexico, some 15 miles south of the U.S.-Mexico border, on July 14, 2010. Gambling their lives, illegal immigrants increasingly are looking to the ocean, as they consider crossing overland even more arduous and more likely to end in getting caught. U.S. agents have arrested 753 suspected illegal immigrants on Southern California shores and seas since October. (AP Photo/Guillermo Arias)
