It uses its venom primarily as a means of defense. The spitting cobra has the ability to direct venom up to three metres away from its location. [1] The trajectory of the venom that the cobra sprays is not at random. The spitting cobra has evolved to aim the venom that it spits into or as close as possible to the antagonist’s face and eyes. [1]
Like most other spitting cobras, its venom is primarily a postsynaptic neurotoxin and cytotoxin (necrotizing or tissue-death). [4] Like all cobras, this species shows variation in venom toxicity based on different factors (diet, locality, etc.). In a study of specimens from Thailand, the IV LD 50 was 0.28 μg/g (0.18-0.42 μg/g). [14]
The venom of the rinkhals is neurotoxic and partially cytotoxic, and is less viscous than that of other African elapids. [6] When confronting a human, it generally aims its venom at the face. If the venom gets injected, it causes great amount of pain and even necrosis due to the cytotoxic effect. If the venom enters the eyes, it causes great ...
The average venom yield per bite is approximately 263 mg dry weight. [22] Between 1968 and 1974, 20 cases of cobra bites were observed in Thailand; all the patients developed systemic envenoming and received treatment, but 19 patients survived. [23] The monocled cobra causes the highest fatality due to snake venom poisoning in Thailand. [24]
The LD 50 in mice, which is used as a possible indicator of snake venom toxicity, is: 0.133 mg/kg intravenous, [26] 0.40 mg/kg intraperitoneal, [27] about 0.75 mg/kg subcutaneous. [28] For most humans, a lethal dose is about 40–70 mg, well within the amount that can be delivered in one bite.
Tom Hardy, from the first "Venom" on, has chosen to offset the uncoolness of doing a comic-book franchise by putting his slumming in quotation marks, playing Eddie as a borderline doofus who talks ...
Rear-fanged snakes need to bite and hold on, or repeatedly bite, to have any effect on humans. A chewing action facilitates envenomation, as the venom ducts open to fangs that are externally grooved (not hollow) and are posterior in the oral cavity. R. subminiatus has enlarged and ungrooved teeth. The species has two enlarged teeth in the back ...
