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

Nola ezagutu

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

Askotan honekin nahasten da: 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

Zer egiten du bere pozoiak?

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

Arriskua pertsonentzat: MingarriaBenetan min handia eman dezake, baina ia inoiz ez da larria.

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

Zer egiten du beldurtzen denean?

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

Utzi tartea. Bat aurkitzen baduzu, egon lasai, egin atzera poliki eta utzi bere bidetik joaten.
