(Courtesy of the Shedd Aquarium)"><br> Caretakers at Chicago's Shedd Aquarium say they have euthanized a 13-year-old male California sea lion named Otis.</p><p>Aquarium officials say they made the decision after the sea lion showed a rapid decline in health due to progressive urogenital cancer. Otis came to the Shedd Aquarium in 2009 as part of a program to relocate sea lions from the Bonneville Dam in Washington state. Dozens of sea lions were endangering fish stocks in the Columbia River.</p><p>Veterinarians say Otis started losing his appetite and showing signs of lethargy a few weeks ago. He was euthanized last week. Shedd Aquarium animal care and training vice president Ken Ramirez said euthanizing the sea lion was a "difficult but necessary decision."</p><p>Shedd has two other male California sea lions named Biff and Tyler.</p></p> Mon, 05 Mar 2012 15:14:00 -0600 http://www.wbez.org/story/sea-lion-dies-chicagos-shedd-aquarium-96961
