Which marine fish has the most venomous spines?

Which marine fish has the most venomous spines? The stonefish has the most venomous spines of any marine fish. The reef stonefish (Synanceia verrucosa) is widely described as the world's most venomous fish, with up to 13 sharp dorsal spines connected to venom glands. When stepped on or threatened, the spines can inject powerful venom through the skin, sometimes even through thin footwear.

Stonefish are ambush predators that sit motionless on the seafloor and blend in with rocks, coral, and algae. Their camouflage is so effective that people are more likely to be injured by accidentally stepping on one than by seeing and approaching it deliberately. They strike prey extremely quickly, swallowing small fish and crustaceans.

Lionfish and scorpionfish are also venomous, but their spines are generally less dangerous. Stingrays deliver venom through a tail barb rather than dorsal spines. Despite its fearsome defenses, the stonefish is still eaten by some predators, including certain rays and sharks. Immediate medical treatment is essential after a suspected stonefish sting.
