The common stingray is a flat, diamond-shaped ray that lives on sandy or muddy seabeds in shallow coastal waters. It is found in the northeastern Atlantic, the Mediterranean and the Black Sea. It has a venomous spine on its tail, which can give a very painful sting.1

Hoe om dit te herken

Diamond-shaped pectoral fin disc that is slightly wider than it is long1
Plain colour: solid grey, brown, reddish or olive-green above, and whitish below with dark fin edges1
Mostly smooth skin; the largest individuals have a row of bony knobs along the middle of the back1
Slender, whip-like tail with a serrated venomous spine about a third of the way along it1

Word dikwels verwar met: The blue stingray of southern Africa was once thought to be a variant of this species, but it is a separate species. The common stingray lacks the blue markings of the blue stingray. Tortonese's stingray of the Mediterranean is similar, and the difference between the two is poorly understood.1

Gifkrag

Steke

Gif kom deur 'n angel uit.

Wat doen sy gif as dit byt of steek?

The venom comes from a gland at the base of a serrated tail spine. A sting causes an excruciatingly painful wound. It is rarely life-threatening.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: Ernstig'n Steek moet deur 'n dokter gesien word. Sterftes is baie skaars.

The common stingray is not aggressive, but it can inflict a very painful wound with its tail spine. The wound is rarely life-threatening.1

As dit 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 een 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
