Antennarius presently constitutes about 11 species of fish in the family Antennariidae. These fish spend most of their lives on the bottom in relatively shallow water between 20 and 100 meters. They can be found worldwide in tropical and subtropical waters. They are ambush predators that wait for prey fish to pass by. They have "lures" which they move to attract the prey. They have little economic value other than a minor role in the aquarium trade.
