Darryl Mhoon rescues a comatose iguana out of a canal after it fell out of a tree in Davie, Florida January 10, 2010. Frigid temperatures below the freezing mark have not been seen in south Florida in 30 years, causing some of the tropical wildlife to either freeze or fall into a sleep-like state because of a drop in body temperature. Mhoon was hoping to bring the iguana home and keep it warm for a few days until temperatures return to normal. REUTERS/Hans Deryk (UNITED STATES — Tags: ANIMALS ENVIRONMENT)
