Question: Which size?

Over 10cm length

Antennarius commerson and Antennarius pictus are the frogfishes most commenly found in Hawaii. They like to sit on exposed areas and are quite large. Unfortunately they both belong to the so called Pictus-group and it is quite difficult to distinguish them. Means of identification for frogfishes of the Antennarius pictus group.

Around 10cm length

Antennatus coccineus and Antennatus nummifer both belong to the genus Antennatus and are difficult to distinguish from each other. Here some characteristics that might help with an identification:

Antennatus coccineus - Lacks distinct tail base (dorsal and anal fins end at base of tail fin)
Antennatus nummifer - has a large darkly pigmented basidorsal spot. The lure can have different shapes, but is mostly small and most of the time round but sometimes with filaments and dark swellings.

Antennatus coccineus (Freckled frogfish)

9-13cm

Antennatus coccineus - Antennarius coccineus - Freckled frogfish (Scarlet frogfish) - Sommersprossen Anglerfisch

Under 10cm length

The following frogfishes are very small and are often overlooked by divers. Only a few pictures exist - so if you have a photo, please write me.

Antennarius randalli is a tiny frogfish and is identified by the round white spots which are positioned on the body and on the tail.

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.
Please take note, that this is a simplified identification key. Ichthyologists use tables with the number of dorsal, anal and pectoral rays, the length of the illicium and other distinguishing characteristics for means of identification.

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.
