Lizard Fish are slender, elongated in shape. They have no fin spines and are 12 to 50 centimeters long. The predators have a deeply split mouth with many fine, very sharp teeth on their tongues.
Lizard fish lie in wait, or buried in the sandy bottom or between coral breaks for their prey, which can consist of small fish such as damselfish, gobies, wrasse but also shrimp or squid. They snap for prey up to their own size.
