The southern stingray is a flat, diamond-shaped fish that lives on the sea bed in warm waters of the western Atlantic Ocean. It hides under sand and mud and is famous for the venomous spine on its tail. Divers and snorkellers often meet it in the Caribbean.1

Tuis

It lives on the sea bed, often in shallow water, and can be found singly or in pairs. In parts of the Caribbean, such as Grand Cayman, Antigua and Turks and Caicos, people meet it at places like Stingray City, the Sandbar and Gibbs Cay, where it swims with divers and snorkellers.1

Gifkrag

Steke

Gif kom deur 'n angel uit.

Wat doen sy gif as dit byt of steek?

The barb on the tail is covered in venomous mucus. The spines are not fatal to humans, but stepping on one causes intense pain.1

Hoe gevaarlik is dit vir mense?

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

The spines are not fatal to humans, but they are incredibly painful if stepped on. They are used to defend the stingray against predators, including humans.1

Wat doen dit as dit bang is?

It buries itself in the sea bed to avoid predators and uses its venomous tail spines to drive them off.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

In shallow waters, birds follow the stingrays as they dig, eating the fish that the stingrays uncover.1

Its eyes and breathing openings sit on top of its head, so it can take in water while lying on the sea bed or buried in sand.1

It senses hidden prey through Ampullae of Lorenzini, which pick up the electric fields that prey give off.1

It is nocturnal, so most of its hunting happens at night.1

Female southern stingrays grow much larger than males.1
