Species often confused with {name}
Warty Frogfish
Antennarius maculatus
Key differences: Generally smaller (up to 15 cm), often has distinct dark spots or blotches, and its esca is typically a tuft of filaments or a small, irregular lump, less complex than A. commerson's. The illicium is usually shorter relative to the second dorsal spine.
Painted Frogfish
Antennarius pictus
Key differences: Similar in size to A. maculatus (up to 30 cm), often has a more 'painted' or marbled pattern. The esca is typically a small, irregular tuft or a single filament, and the illicium is usually shorter than the second dorsal spine. A. commerson generally has a more robust and less compressed body.
Sargassum Frogfish
Histrio histrio
Key differences: While also an anglerfish, H. histrio is specifically adapted to live in Sargassum weed, possessing highly branched appendages and a coloration that perfectly mimics the algae. It is pelagic, unlike the benthic A. commerson. Its illicium is also shorter and its esca is a small, leaf-like appendage.
