Stone fish

The stonefish (Synanceja verrucosa) is primarily brown or gray, camouflaged to blend in with the rocky sea bottom. It is native to the Indo-Pacific region. Characterized by its distinctive warty skin and robust, angular body, this fish is notorious for being the most venomous fish in the world. Despite its infamy, it is not commonly kept in the aquarium hobby due to its specialized care requirements and potential danger to handlers.
