The lesser weever is a small, venomous fish that lies buried in sand on the sea floor, often close to the shore. Its venom is strong, and it is considered one of Europe's most dangerous weever species because it lives near beaches where people swim.1

Leef in

Eastern Atlantic from the North Sea around the British Isles to Morocco and Madeira, and the Mediterranean1

Atlantiese Oseaan, Middellandse See, Noordsee

Tuis

It lives on sandy and muddy sea beds in the open sea, near the shore, from a few metres deep down to 150 m in winter. People meet it when swimmers disturb it in the water and when fishermen clean their nets.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 venom contains trachinine, a cytolysin (a substance that breaks down cells), along with serotonin, histamine-releasing substances and various enzymes. The sting causes acute and intense pain that often spreads to the area around the limb, and it peaks about 30 minutes after the sting. Swelling, redness, numbness, tingling, nausea and vomiting are common, and rare severe effects include abnormal heart rhythms, seizures, decreased blood pressure and unconsciousness.1

The lesser weever can sting swimmers badly if they disturb it in the water, and fishermen can be stung when cleaning their nets. Because of its venom and its occurrence near beaches, it is considered one of Europe's most dangerous weever species. Some pain may continue for up to 24 hours.1

Wat doen dit as dit bang is?

It rests buried in the sand with only its eyes and the tip of its first dorsal fin exposed, and it stings when disturbed.1

As sy stekels jou steek

Wash the wound, then immerse it in very hot water for at least an hour to ease the pain and help destroy the protein-based venom. The water should be 40 °C (104 °F) or as hot as the patient can tolerate. Reassure the patient that the sting is relatively harmless.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
