The marbled spinefoot is a shoaling fish that mostly eats algae. It lives in shallow warm seas in the Red Sea and western Indian Ocean, and it has spread into the Mediterranean. Its spines carry venom, so it is one to leave alone.1

Wat eet dit?

Adults mainly graze on algae, including Polysiphonia and Sphacelaria species. In spring and early summer in the northern Red Sea they have also been seen eating comb jellies and moon jellyfish. Young fish feed on tiny diatoms and then on small crustaceans called copepods.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?

The spines in the fins have venom glands at their base. The venom is a protein that is damaged by heat. The sting is very painful.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: PynlikDit kan regtig seermaak, maar dit is amper nooit ernstig nie.

The spines can inflict a painful sting if the fish is handled incorrectly. No deaths from its venom have been recorded. Separately, poisoning has been recorded in Israel after people ate its flesh, linked to fish caught in polluted water.1

Wat doen dit as dit bang is?

Its spines are barbed and venomous, and they can injure anyone who handles the fish carelessly.1

As sy stekels jou steek

The affected area should be treated with as high a temperature as possible, within 43 to 46 °C, because heat damages the venom. The person should also be checked for possible infection.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

Feite

Some people have reported hallucinations after eating it.1

Eating its flesh has caused poisoning, and the toxins involved are similar to ciguatoxin.1
