The Red Sea stonefish is a small, venomous fish that hides among rocks and coral in warm, shallow sea water. Its grey, bumpy body looks like the stones around it, so it is easy to miss. Its dorsal spines carry venom, so it is important to know what it looks like.1

Its venom is a presynaptic neurotoxin, which disrupts nerve signals. The venom is released from glands when its erected dorsal spines are pressed with force.1

The Red Sea stonefish is hazardous to people because of the venom in its dorsal spines.1

E etsang ha e tshohile?

When threatened, it erects its dorsal spines, and relies on its camouflage to stay hidden.1

Dintlha

1

When it feels threatened, it raises its dorsal spines. Venom flows out of glands when force is applied to the spines.1

2

Its venom is protein based, so cooking can break it down.1

3

Its slimy coat collects algae and sand, which helps it blend into the seabed.1

4

Sharks, rays and sea snakes prey on stonefish. Their venom may work less well against these predators.1

5

Close relatives are not used in the legal aquarium trade because they are so venomous, and handling them needs great care.1
