Recognizing and Treating Weever Fish Stings

Fact Checked

Weever fish stings are amongst the venomous stings

in the temperate zone. The weever fish, sometimes also spelled as weaver fish, is considered more venomous than many jellyfish and as poisonous as the stingray. The highly dangerous fish are primarily found near the beaches or shorelines as they live in warm shallow water. Weever fish are docile and attack only when they feel provoked. They are sometimes called “sea dragon,” “sea cat,” “stang” and “adder-pike.”

Weever fish usually have a sandy brown appearance and typically camouflage withthe sand. Their poisonous spines, which inject the venom to their victims, are located on their first dorsal fin and gills. Each weever fish has four to eight long “spines.” Weever fish are usually buried in the sand, thus the most common sting sites are the feet and hands, when they are stepped on. Although they are extremely undesirable, weever fish stings do not usually cause serious harm and pain eventually subsides within a few hours even if they untreated.Fishermen and tourists are their most frequent victims. Fortunately, chances of getting stung are relatively low.
