1. Camouflage:
* Appearance: They resemble rocks, blending seamlessly with their surroundings. They can even change their color to match their environment.
* Immobility: Stonefish stay perfectly still for long periods, making them incredibly difficult to spot.
2. Venomous Spines:
* Location: Stonefish have 13 sharp, venomous spines on their dorsal fin, as well as some on their pectoral fins and operculum (gill cover).
* Venom: Their venom is extremely potent, causing excruciating pain, tissue damage, and even paralysis. It can be fatal if not treated immediately.
* Delivery: When threatened, they erect their spines, ready to inject venom if stepped on or touched.
3. Other Defense Mechanisms:
* Warning: Stonefish may also puff themselves up and make a hissing sound as a warning to potential predators.
Important Note: If you encounter a stonefish, do not touch it. Seek immediate medical attention if you are stung.
