About this species

Inimicus filamentosus, also known as the filament-finned stinger, barred ghoul, two-stick stingfish, or devil scorpionfish, is a member of the Inimicus genus of venomous fishes. It is a member of the Synanceiidae family of the Scorpaeniformes order of ray-finned fishes. These benthic fishes are found on sandy or silty substrates of lagoon and seaward reefs, in coastal regions of tropical oceans. Like all the other known species of Inimicus, I. filamentosus is a demersal ambush predator. They are nocturnal, and often dig themselves partially into the sandy seabed during the day.
