Elementor #921 – Wild Blue Scuba

Stone Fish

The most well-known species is the Reef Stonefish (Synanceia verrucosa). Other species include:

There are around 5–6 species of stonefish, mainly from the Synanceia genus. They are all venomous and share similar camouflage abilities.

Found in tropical and subtropical waters of the Indo-Pacific region.
Typically reside in coral reefs, rocky seabeds, estuaries, and shallow coastal waters.
Prefer areas with rubble, sand, or seagrass where they can blend in perfectly.
Can sometimes be found in mangroves and tidal pools.

Carnivorous; ambush predators.
Feed on small fish, shrimp, and crustaceans.
They wait motionless and strike with a rapid suction that is one of the fastest predatory movements in the ocean (as fast as 0.015 seconds).

Male and female stonefish look very similar, making them hard to distinguish.
Females tend to be slightly larger than males.
Reproduction is oviparous (egg-laying), with females laying eggs that males externally fertilize.

Appearance:
- Warty, bumpy, and textured skin, covered in algae and sand to blend in with the surroundings.
- Brown, gray, reddish, or mottled coloration to resemble coral or rocks.
- Small upturned mouth and tiny eyes on the top of the head.
Behavior:
- Sits motionless for long periods.
- Rarely moves unless disturbed or hunting.
- When threatened, it may raise its 13 venomous spines on its dorsal fin as a defense mechanism.
Warning Sign:
- If stepped on, the stonefish injects potent neurotoxic venom, which can cause excruciating pain, swelling, tissue necrosis, paralysis, and even death if untreated.
