The venom of this species is much less viscous than that of different African elapids, naturally, as thinner fluid is simpler to spit. However, the venom of the rinkhals is produced in copious amounts. Average venom yield is eighty–one hundred twenty mg and the murine LD50 is 1.1-1.6 mg/kg SC with an estimated deadly dose for humans of fifty–60 mg. Actual bites from this species are fairly … Read More

An average moist venom yield of one hundred mg has been reported for this species. The common murine LD50 worth of this species is 1.15 mg/kg IV, however there may be an IV LD50 range of 0.97 mg/kg-1.45 mg/kg. The West African spitting cobra is one of the most typical causes of snakebite in Senegal.

A muscular diaphragm separates the center and the lungs from the abdominal cavity. Mature purple blood cells (erythrocytes) in all mammals lack a nucleus; all other vertebrates have nucleated purple blood cells. The oldest identified animals categorized as mammals advanced near the boundary of the Triassic and Jurassic Periods, some 200 million years ago.
