Description
The Tonga fangblenny is a fangblenny (Blenniidae) from the southwest Pacific, around Tonga. The species grows to about 10 cm and has a slender, blue body. The blue-grey body bears fine longitudinal markings. In the lower jaw it bears two large, venomous canine teeth; on a bite the venom delivers a numbing, painful jab that makes predators release it.
