Rock fish Rock fish is a kind of fish with strong toxicity in nature, and its "deadly sting" is described as the most painful sting of human beings. The stone fish is not surprising in appearance, only about 30 centimeters 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 release deadly venom. The backstab from 12 to 14 on its back, as sharp as a needle, will easily penetrate and pierce the soles of the feet, causing people to be poisoned quickly and remain in severe pain until death.
