Species often confused with {name}
Blackbelly Rosefish
Helicolenus dactylopterus
Key differences: While also benthic and somewhat camouflaged, the Blackbelly Rosefish has a more typical fish body shape, prominent scales, and lacks the distinctive illicium and flattened head of the anglerfish.
Skates and Rays
Rajiformes
Key differences: Skates and rays are cartilaginous fish (Chondrichthyes) with flattened bodies and large, wing-like pectoral fins fused to the head. Anglerfish are bony fish (Osteichthyes) with a distinct head and body, and their pectoral fins are not fused in the same manner. Anglerfish also possess the illicium.
European Anglerfish
Lophius piscatorius
Key differences: The European Anglerfish is very similar in appearance and behavior. Differentiating features are subtle and often require examination of vertebral counts, fin ray counts, and specific anatomical proportions, particularly of the illicium and esca. Generally, L. americanus has a shorter illicium relative to head length and a more complex esca than L. piscatorius.
