Cowtail stingray
The cowtail stingray is a large ray that lives in warm coastal seas and sometimes swims up rivers. Its most noticeable feature is a wide, flag-like fold of skin on its tail. It has a venomous spine on its tail, so it should be left alone.1

Hoe om dit te herken
- A large, flag-like fold of skin on the underside of the tail, which is especially prominent when the ray swims1
- Grey-brown to black on top and mostly white below1
- Black tail fold and tail tip1
- A thick, rounded pectoral disc with a blunt snout and very small, widely spaced eyes1
- A single venomous spine set well back on the tail1
Gifkrag
Gif kom deur 'n angel uit.
Hoe gevaarlik is dit vir mense?
Gevaar vir mense: Ernstig'n Steek moet deur 'n dokter gesien word. Sterftes is baie skaars.The serrated spine is potentially dangerous, and the cowtail stingray is regarded as particularly dangerous to handle.1
Wat doen dit as dit bang is?
When threatened, it flees at a 45° angle away from the predator, keeping the predator in view while covering distance.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
A cowtail stingray was recorded in the Ganges River about 2,200 km (1,400 mi) from the sea.1
Resting groups of cowtail stingrays often form a rosette, with their tails pointing outward so they can see threats from every direction.1
Its large, regularly arranged skin bumps have made it a source of shagreen leather since ancient times.1
The cowtail stingray and reticulate whiprays often form mixed-species groups, probably because the whiprays detect predators well thanks to their long tails.1
Its tail fold and tail tip are black, and the tail carries sensors that act as a secondary warning system.1
Newborn cowtail stingrays have completely smooth skin, and their denticles develop quickly after birth.1
