stonefish

Deadly reef lurker

Stonefish are venomous fish found in shallow coastal waters of the Indo-Pacific.

They're considered among the most venomous fish in the world.

Their camouflage resembles rocks or coral on the seafloor, making them nearly invisible—and dangerously easy to step on.

Spines along the dorsal fin inject venom that causes intense pain and can be fatal without treatment.
