The desert cobra is highly venomous. The subcutaneous LD 50 for the venom of W. aegyptia is 0.4 mg/kg. For comparison, the Indian cobra's (Naja naja) subcutaneous LD 50 is 0.80 mg/kg, while the Cape cobra's (Naja nivea) subcutaneous LD 50 is 0.72 mg/kg. This makes the desert black snake a more venomous snake than both. [3]
