The Warty Frogfish, Antennarius maculatus, are some of the most cryptic predators found on tropical reefs around the world. Many species of frogfish have markings that blend them in perfectly with the corals, sponges, and coraline algaes comprising tropical reefs. Many species can change the colour and even the cryptic patterns on their bodies, depending on the substrate where they reside. The disguise hides them from potential predators and potential prey. Frogfish have a fishing pole-like structure, the illicium, that emerges from their head and can be rocked back and forth. At the end of the pole is a structure known as an esca. The esca is the equivalent of a lure, which attracts small prey by mimicking a potential food item like a shrimp or small.
