The estuarine stonefish is a fish that looks like a stone lying on the seabed. It lives in shallow reefs and estuaries across the Indo-Pacific, including northern Australia. It is considered one of the most dangerous venomous fish in the world, so it is important to know what it looks like.1

Gifkrag

Giftige stekels

Skerp stekels dra die gif. Dit maak seer as jy daarop trap of dit gryp.

Each fin spine has two venom-producing glands. The venom affects the cardiovascular and neuromuscular systems. The sting is extremely painful and has been known to be lethal.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: Baie gevaarlikDit kan 'n mens doodmaak wat geen behandeling kry nie.

It is considered one of the most dangerous venomous fishes. Stings are extremely painful and have been known to be fatal. Since European settlement, there have been no recorded deaths in Australia from stonefish venom, but deaths have been recorded elsewhere in its range.1

Goeie nuus: dokters het 'n medisyne (teengif) of 'n behandeling hiervoor.1

Wat doen dit as dit bang is?

When disturbed, it erects its venomous spines, which inject venom if the fish is stepped on.1

As sy stekels jou steek

Antivenom can be given after envenomation. Immersing the sting wound in hot water can be used to denature the venom.1
Sit die wond in warm water, so warm as wat die persoon kan verdra sonder om te brand (toets dit met jou eie hand), vir 30 tot 90 minute. Kry mediese hulp, veral vir klipvisse en pylsterte.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As sy stekels jou steek: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly
