Last updated
via Wikipedia: Spotfin frogfish · see source
Georges Cuvier, a French zoologist, originally described this marine anglerfish as Chironectes nummifer in 1817, with no known type locality.[1][2] The genus name Abantennarius incorporates the prefix ab- (meaning "away from") with antennarius, indicating that the gill opening is situated away from the pectoral fin base, unlike most frogfishes.[3]

Biology and range
A dark spot surrounded by an indistinct greenish ring is almost always present at the base of the second dorsal fin.[4] The larvae are planktonic for 1 to 2 months before settling onto reefs.[5]
What the specialist sources record
The Fishes of Australia account notes that spotfin anglerfish vary in color to match their surroundings, ranging through mottled yellow, orange, pink, red, brown, and black.[2] The same source describes them as well-camouflaged ambush predators.[2] The Fishes of Australia account also states that the species is widespread throughout the tropical Indo-Pacific, from the Red Sea and East Africa to Central America in the Eastern Pacific.[2] The World Register of Marine Species lists the accepted name as Abantennarius nummifer (Cuvier, 1817) in the family Antennariidae, order Lophiiformes.[6]
GBIF treats this name as a synonym and holds 67 occurrence records for the taxon as of October 2026.[7]
