We can’t help but smile after seeing this big grin from one of the fishes at Florida Keys National Wildlife Refuge Complex. Comprised of four refuges situated in the Florida Keys, the complex protects the critical habitats on the land and in the water for wildlife like the American crocodile, the endangered Key deer, the Great White Herons and others.
