See text Synanceiinae is a subfamily of venomous ray-finned fishes, waspfishes, which is classified as part of the family Scorpaenidae, the scorpionfishes and their relatives.

Its species are known to have the most potent neurotoxins of all the fish venoms, secreted from glands at the base of their needle-like dorsal fin spines.

Synanceiinae, or the family Synanceiidae, was first named and recognised as a grouping of related taxa by the English naturalist William Swainson in 1839.

[3] Other authorities differ in their treatment of this grouping, regarding Synanceiidae as a valid family within the suborder Scorpaenoidei which they include in the order Perciformes, treating the tribes as subfamilies.

[3] Synanceiinae species are found in the Indian and Western Pacific Oceans, including the Red Sea.
