Frogfish are highly effecient ambush predators who use a special organ which consists of two parts, the rod (illicium) and the lure (esca), to attract prey.

The frogfish's mouth and stomach can expand an astonishing amount, allowing the frogfish to swallow prey more than twice its size. We photographed this one in Anilao, Philippines.
