- Stonefish serves as the collective name of any of 5 species found in the family listed as Synanceiidae. All five known varieties in the family also rank as highly venomous. In fact, they rank among the most poisonous fish known on earth.
- Its name derives from the unique appearance of all varieties. This represents a rather remarkable adaptation allowing them to camouflage themselves into the surrounding rocky areas they prefer to inhabit. Their varied colors and mottled appearance also help make them extremely difficult to spot and avoid.
Stonefish Physical Description
Physical appearance varies between the different forms of Stonefish, yet some patterns exist. All members of this impressive family display rough, mottled appearances and uneven lines. These traits allow for better camouflage in their native habitat.
Every variety also possesses powerful toxins. The venom of the creature forms in the spines on the fins, which stick up when threatened.
Their venom is extremely dangerous, excruciatingly painful, and can be fatal. In fact, PADI lists them as the most venomous fish in the world.
Stonefish Distribution, Habitat and Toxin
All known types of Stonefish evolved primarily as marine fish. However, they will sometimes also inhabit rivers, in the areas where they meet the ocean and the waters blend.
These fish do not generally display overtly aggressive behavior by nature. Most envenomings occur when unsuspecting swimmers simply step on the fish.
