Wat eet dit?

It eats mostly small fish, shrimp and other crustaceans. It sits motionless on the reef floor and waits for prey to swim past, then engulfs it at great speed. Some have struck prey in 0.015 seconds.1

Gifkrag

Giftige stekels

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

Wat doen sy gif as dit byt of steek?

Its venom is a mixture of proteins. Effects include severe pain, shock, paralysis and tissue death. A large dose can be fatal, and the fatal protein in this species is verrucotoxin. Stonefish venom can be fatal at a dose of only 18 mg, which six of its thirteen spines can release.1

Hoe gevaarlik is dit vir mense?

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

It is the most venomous fish in the world and its venom can kill humans. A large dose can be fatal, and young children, the elderly and people with weakened immune systems are at greatest risk.1

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

Wat doen dit as dit bang is?

It relies on camouflage to stay hidden and, when necessary, on its back spines, each with venom sacs at its base.1

As sy stekels jou steek

Immerse the affected limb in hot water, which is thought to help break down the venom proteins. A local anaesthetic can reduce the pain, and medical treatment includes antivenom. A tourniquet or firm constrictive bandage is no longer recommended.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
