Hoe om dit te herken

  • Blue-grey to dark brown on the back, with a light grey belly.1
  • Deeply forked tail.1
  • Long, serrated venomous spines on the pectoral and dorsal fins.1
  • A small hump on the back that looks somewhat like a wave.1
  • A white or pale blue anal fin, and a fleshy extension on the dorsal spine.1

Word dikwels verwar met: It resembles the hardhead catfish. The gafftopsail can be told apart by the distinctive fleshy extension on its dorsal spine.1

Hoe gevaarlik is dit vir mense?

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

The spines can cause painful wounds, so care should be taken when handling this fish.1

As sy stekels jou steek

  • 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
