Naja is a genus of venomous elapid snakes commonly known as cobras (or "true cobras"). Members of the genus Naja are the most widespread and the most widely recognized as "true" cobras. Various species occur in regions throughout Africa, Southwest Asia, South Asia, and Southeast Asia.
The Chinese cobra is a highly venomous member of the true cobras (genus Naja). [14] The murine LD 50 values of its venom are 0.29 mg/kg IV [15] and 0.53 mg/kg [5] —0.67 mg/kg SC. [15] The average venom yield from a snake of this species kept at a snake farm was about 250.8 mg (80 mg dry weight).
α-Cobratoxin is a neurotoxin from the venom of certain Naja genus, including the Thailand cobra, the Indochinese spitting cobra (Naja siamensis) and the Chinese cobra (Naja atra). The cobras that produce the toxin live in tropical and subtropical regions of Africa and Asia.
This species should not be confused with the monocled cobra (Naja kaouthia), which has similar habitat, size and appearance. Another distinguishing feature is that this species is a "true spitter"; it readily spits venom, but rather than a stream of venom as seen with many other "spitting cobras", this species ejects a "mist" rather than a ...
The monocled cobra (Naja kaouthia), also called monocellate cobra and Indian spitting cobra, is a venomous cobra species widespread across South and Southeast Asia and listed as Least Concern on the IUCN Red List.
The Caspian cobra (Naja oxiana), also called the Central Asian cobra or Russian cobra, is a species of highly venomous snake in the family Elapidae. The species is endemic to Central Asia . First described by Karl Eichwald , a German physician, in 1831, it was for many years considered to be a subspecies of the Naja naja until genetic analysis ...
Chinese cobra (Naja atra) The Chinese cobra (Naja atra) is a highly venomous member of the true cobras (genus Naja). Its venom consists mainly of postsynaptic neurotoxins and cardiotoxins. Four cardiotoxin-analogues I, II, III, and IV, account for about 54% of the dry weight of the crude venom and have cytotoxic properties. [126]
Although venom toxicity values can vary greatly even among specimens of the same species, the Philippine cobra is considered to possess one of the more toxic venoms among the Naja (cobra) species. According to Tan et al., the murine LD 50 via the IV route for this species is 0.18 mg/kg (0.11-0.3 mg/kg). [10]
