The round ribbontail ray is a large stingray that lives in warm, shallow seas across the Indo-Pacific, from South Africa to Japan and Australia. It can grow to 1.8 m across, and it is valued by divers for its size and striking look. It has a venomous tail spine, so it is one to admire from a distance.1

Hoe gevaarlik is dit vir mense?

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

It is not aggressive and has been known to approach and investigate divers. If harassed, it can inflict a severe wound with its venomous tail spine. At least one diver has died after being stabbed while trying to ride one.1

Wat doen dit as dit bang is?

When threatened, it raises its tail over its back with the spine facing forward and waves it back and forth.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

Feite

It is one of the largest stingray species, reaching 150 kg in weight.1

Females can be pursued by dozens of males during reproductive gatherings, which have been seen in groups of hundreds at Cocos Island.1

Smaller fishes such as jacks and cobia often follow it, feeding on food stirred up by its movements or sheltering behind its body.1

It is mostly active at night and rests motionless during the day, often in caves or under ledges.1
