The frogfish (or anglerfish, angler, fishing frog) is one of my favorite fishes so this website is dedicated entirely to this family of fishes (Antennariidae).
Frogfishes 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 dangled, flicked and 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. With this kind of luring behavior the frogfish is a very succesfull predator.
Although like a lot of divers I have started to use the nickname "Froggie" of course the frogfish is not exactly a cuddly animal - actually it is not very likable - but but how it looks and it's behavior is very interesting!
IMPORTANT: Based on new findings (reference)
about DNA in frogfishes the nomenclatur for several frogfish species (all
of the former genus Antennarius) was changed and this website corrected
accordingly in 2012.

I identified all frogfishes (anglerfishes) to my best knowledge. Frogfishes are specially difficult to identify (see tips for identification) so mistakes are possible of course! Please write to me, if you have any questions or you would like to send me photos of frogfishes. Latin names according to the newest scientific findings, ITIS Standard Report and Fishbase.
