Stonefish has deadly venom, which can cause swelling, tissue necrosis, paralysis, shock and then death.

The stinger of stone fish is such a magic weapon. There are not only sharp spines on the dorsal fin of the stone fish, but each thorn is also connected with the poisonous glands on the back. When the stone fish is disturbed, these stingers on its back will stand up and face the enemy.

Characteristics of the stone fish:

The stone fish is unremarkable in appearance, only about 3 cm long, and likes to hide under the sea floor or rocks and disguise itself as an inconspicuous stone.

If someone does not pay attention to stepping on it, it will immediately fight back rudely and emit deadly poison. The 12 to 14 needles-sharp backstab on its back will easily penetrate the sole and pierce the sole of the foot, causing people to be poisoned quickly and remain in severe pain until death.
