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

Sihlala

Red Sea and Persian Gulf, in the western Indian Ocean1

Ekhaya

It lives hidden among rocks and coral in shallow salt water, at depths between 3.5 and 18 metres. It prefers warmer water, roughly 26 °C to 30 °C.1

Ubude

Sitya ntoni?

It is an ambush predator. It half-buries itself or sits between rocks, waiting for prey to pass close by.1

Amava anetyhefu

Amava abukhali aphethe ityhefu. Ukusinyathela okanye ukusibamba kubuhlungu.

Ityhefu yaso yokuluma okanye yokuhlaba yenza ntoni?

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

Siyingozi kangakanani ebantwini?

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

Senza ntoni xa soyika?

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

Ukuba amava aso ayakugwaza

Faka inxeba emanzini ashushu, ashushu kangangoko umntu angakwazi ukunyamezela ngaphandle kokutshiswa (wavavanye ngesandla sakho), imizuzu engama-30 ukuya kwengama-90. Fumana uncedo lwezonyango, ingakumbi kwii-stonefish nakwii-stingray.

Soloko utsalela inombolo kaxakeka kuqala (112, 000, 911). Esi sisikhokelo soncedo lokuqala ngokubanzi, asilocebiso lwezonyango. Iziseko zoncedo lokuqala

Hlala ukhuselekile

Ungaze uchukumise, ubambe okanye uqhule isilwanyana sasendle, nokuba sincinci, kwaye nokuba sibonakala silele okanye sifile.
Sinike indawo. Ukuba udibana naso, hlala uzolile, buyela umva kancinci kwaye usiyeke sihambe ngendlela yaso.
Ukuba amava aso ayakugwaza: hlala uzolile, musa ukushukuma, tsalela inombolo kaxakeka (112, 000, 911) okanye uye esibhedlele ngokukhawuleza. Khumbula ukuba sasikhangeleka njani, ifoto iyanceda.

Asikuzingeli. Sisebenzisa ityhefu yaso ukubamba ukutya okanye ukuzikhusela, kwaye singakhetha ukuzimela. Okungakumbi malunga nokuhlala ukhuselekile

Iinyaniso

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

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

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

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

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