Frogfishes are bottom-dwellers ranging from shallow inshore areas to deep waters. They often hide in the sediment or in rock crevices. They are rather sluggish in their movements and are ambush predators, feeding mainly on molluscs and crustaceans. They might bite and their spines may inflict wounds to people handling them.
There are 22 genera and about 80 species worldwide. Malaysia has 4 of these species.
