The rhombic night adder is a venomous snake found across much of Sub-Saharan Africa. It is the largest snake in its genus, Causus, and it has a striking threat display that makes it look more dangerous than its venom usually makes it.1

Hoe om dit te herken

The main colour is usually a shade of brown, sometimes pinkish or greyish, and occasionally olive green.1
It has 20 to 30 rhombic (diamond-shaped) blotches with pale edges running along its back.1
Oblique black bars on its sides are each topped by one or two black spots with pale centres, which look like eyes.1
The head has a V-shaped mark that may be solid black, or brown with a black outline.1
Northern populations may have no pattern at all, which makes them harder to identify.1

Word dikwels verwar met: The common egg-eater (Dasypeltis scabra) is compared with this snake. Its colour pattern and behaviour may be a form of defensive mimicry, meaning it may resemble another animal to stay safe.1

Gifkrag

Byte

Gif kom deur sy giftande of tande uit wanneer dit byt.

Wat doen sy gif as dit byt of steek?

The venom is low in toxicity. Bites usually cause pain and minor swelling, with little tissue death (necrosis), and these symptoms usually fade within 2 to 3 days. Bites can still be serious, as in at least one case where a child needed a fasciotomy, a surgical operation to relieve pressure in a limb.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: PynlikDit kan regtig seermaak, maar dit is amper nooit ernstig nie.

Most individuals are docile and seldom bite unless severely provoked. Bites can be serious, but there are no modern, well-documented cases of deaths from this species.1

Wat doen dit as dit bang is?

When seriously disturbed, it coils up, inflates its body so the dark markings stand out, hisses and puffs loudly, flattens the front of its body and neck, and strikes frantically.1

As dit byt

Hou die persoon stil en kalm, hou die gebyte arm of been op hartvlak, haal ringe en stywe goed af, en kom vinnig by 'n hospitaal uit.

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 byt: 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
