Frogfish, Antennarius sp., are some of the most cryptic predators found on tropical reefs around the world. Many frogfish have markings that blend them in perfectly with the corals, sponges, and coraline algaes. Many frogfish 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 equivalent of a lure, which attracts small prey by mimicking food like a shrimp or small fish. The potential prey are drawn to within striking distance of the frogfish' cavernous mouth, which is opened rapidly, drawing in water and the prey item. Larval anglerfishes are enveloped in a jelly casing. This is a larvae from the family Antennariidae. It was trawled up.
