(Causus rhombeatus) Rhombic night adder, demon night adder, Cape night adder, African night adder, Cape viper
Rhombic Night Adder bites can be very serious and in at least one bite a child had to have a fasciotomy. We see a number of small dogs dying and having limbs amputated. A bite from a large individual on a small child could potentially be fatal - please do not underestimate the venom of this snake.
The few documented bites involved pain and minor swelling with minimal necrosis. These symptoms usually disappear within 2–3 days. There have been no modern well-documented cases to back up earlier claims of fatalities due to bites from this species. Venom yield has varied from 20–30 mg to 300 mg, but the venom toxicity is low with LD50 values of 10.8, 14.6, >16.0 mg/kg IV and 15 mg/kg SC being reported.
No reliable reports of fatalities. No known antivenom currently being produced.
