Frogfish, named for their resemblance to bullfrogs, use camouflage to hide from predators as well as to attract prey. The frogfish takes on the appearance of surrounding objects such as rocks, sponges, and corals and waits until an unsuspecting creature is within reach. It also has another unique way of drawing its prey: it uses a rod-like appendage called the illicium that holds an esca, or bait. Once the frogfish attracts a small sea creature into range with its lure, it blows up to 12 times its normal size and takes a giant gulp, swallowing its prey and gallons of seawater.
