Frogfish are determined by looking at the length of the rod and the form of their lure, the dermal spinules, the number of their spines, the number of fin-rays and the position of the gill opening. It is also important if there are eye spots (ocellus) present or they are missing. The colors are so variable, that they don't help much in identifying frogfishes. Some of the more uncommon colors can be used though to prove or disprove a certain identification.
If you want to find out which species of frogfish you have found, you should look closely and memorize or take a photograph of the following characteristics:
Key to the known Frogfish species
You have found a perticular frogfish and would like to know which species it belongs to. This identification key guides you step by step towards a possible identification.
This identification key is only for species of the subfamily Antennariinae (frogfishes, family Antennariidae, suborder Antennarioidei) which are frogfishes living in tropical and subtropical waters.
There are several species of fish that look very similar to frogfishes. Here a couple examples.
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. Latin names according to the newest scientific findings, ITIS Standard Report and Fishbase.
