A caiman rescued by the ARCAS organization in Guatemala gets the eye  from a ring of turtles. Founded in 1989, ARCAS strives to rehabilitate  animals seized from poachers and illegal pet traders, eventually  releasing most back into the wild. As one of hundreds of travelers  fortunate enough to volunteer at ARCAS each year, I spent long, hot, but  enjoyable days cleaning and feeding parrots, scarlet macaws, spider monkeys, howler monkeys, and other species under pressure in Central America.
