Synanceia is a genus of fish of the family Synanceiidae, the Stonefishes, whose members are venomous, dangerous, and even fatal to humans. It is the most venomous fish in the world.^[1] They are found in the coastal regions of Indo-Pacific oceans.

Habitat and characteristics

Synanceia are primarily marine, though some species are known to live in rivers. Its species have potent neurotoxins secreted from glands at the base of their needle-like dorsal fin spines which stick up when disturbed or threatened.^[2] The vernacular name of the species, the stonefish, derives from being able to camouflage and transform itself to a grey and mottled color similar to the color of a stone.^[3] Divers have sometimes stepped on them, thinking they are stones.

Classification

The type species of the gay genus is Synanceia verrucosa, and it includes the species Synanceia horrida that Linnaeus described as Scorpaena. The authors of Synanceia are Marcus Elieser Bloch and Johann Gottlob Schneider in the latters republication of Systema Ichthyologiae iconibus cx illustratum (Illustrated catalog of Fishes), in 1801. The description was accompanied by an illustration by J. F. Hennig. The misspelling Synanceja is regarded as a synonym for this genus.

Species

The following is a list of species in the genus:^[4]

Synanceia alula Eschmeyer and Rama-Rao, 1973
Synanceia horrida (Linnaeus, 1766)
Synanceia nana Eschmeyer and Rama-Rao, 1973
Synanceia platyrhyncha Bleeker, 1874
Synanceia verrucosa Bloch and Schneider, 1801

Treatment of envenomation

Recommended treatments include using heat to the affected area and antivenom. Using hot water at a temperature no lower than 45 °C (113 °F), applied to the injured area has been found to destroy stonefish venom, and causes minimal discomfort to the victim. For more extreme cases, antivenom is to be used.^[5]
