The Montanez family said the meat tastes like chicken as long as its marinated in lemon or orange juice to first take away the fishy taste. Then they fry it, sautee it or grill it. What the family doesnt eat is sold to interested buyers. (AP Photo/Ricardo Arduengo)
In this Dec. 5, 2012 photo, caimans are kept in a holding tank in the backyard of the Montanez family home before being killed to sell for human consumption in the Los Naranjos neighborhood of Vega Baja, Puerto Rico. Caimans are native to Central and South America, but were introduced to Puerto Rico by stores such as Woolworths that sold baby caimans the size of lizards as pets during the 1960s and 70s, Atienza said. When the caimans began to grow, people released them into the wild, where females rapidly reproduced, laying up to 40 eggs at a time. (AP Photo/Ricardo Arduengo)
