Gecko tails serve many purposes. They help balance their weight as they climb branches, they act as fuel tanks to store fat, and as camouflage to help them disappear into their environment. Geckos are also able to shed their tails if a predator grabs them. Most geckos are nocturnal, which means they are active at night, but day geckos are active during the day and nibble on insects, fruits, and flower nectar. Most geckos make noises such as chirping, barking, and clicking when they are defending their territory or attracting a mate. Hanging your metal art is easy, once you know how. Choose a place it within two design elements that are touching or notched toward the center of the piece and drive a nail into the wall at that point. Using a second and possibly a third nail, place those in other notched areas within the design to secure it firmly. Avoid placing nails in the eyes or mouth. A viewer's eye will go straight to those elements and a nail there will draw attention to itself. You don't want the nails to become part of the details - you want them to "disappear."
