Description

The Freshwater fangblenny is a fangblenny (Blenniidae) from coastal and brackish water of the Indo-West Pacific. The species grows to about 7 cm and has a slender, greyish body. The greyish body is fairly plain with a yellowish tinge. 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. To humans the bite is unpleasant but rarely serious; handle with care.
