(Naja nivea) Cape cobra

The Cape cobra is regarded as one of the most dangerous species of cobra in all of Africa, by virtue of its potent venom and frequent occurrence around houses. The venom of this snake tends to be thick and syrupy in consistency and dries into shiny pale flakes, not unlike yellow sugar.

The Cape cobra’s venom is made up of potent postsynaptic neurotoxins and might also contain cardiotoxins that affect the respiratory system, nervous system, and the heart. The mouse SC LD50 for this species’ venom is 0.72, while the IV and IP LD50 values are 0.4 mg/kg and 0.6 mg/kg, respectively. The average venom yield per bite is 100 to 150 mg (according to Minton). The mortality rate for untreated bites is not exactly known, but is thought to be high.

Tiger Rattlesnake (Crotalus tigris)

Arizona: August 2011

From the best night of field herping I’ve ever had (legal road cruising inside a park after hours right after a rain with a group of amazing herpetologists).
