The frogfishes (or anglerfishes) are fascinating animals. They sit well camouflaged and without moving on sponges, wait in front of holes or hide between corals and wait for their prey to approach. One of its dorsal spine is converted into a lure (illicium) with a bait (esca) which looks like a small fish, a worm or a shrimp. This lure is moved around in front of the Frogfish’s head. If a fish wants to catch this make-believe prey it becomes prey itself – fast as lightning the Frogfish greatly expands its oral cavity thus creating suction pressure inside the mouth and engulfs the animal. This behavior is called aggressive mimicry.
