Cobra is the common name of various elapid snakes, most of which belonging to the genus Naja.[1]

Biology

All of the known cobras are venomous and many are capable of rearing upwards and producing a hood when threatened.[2]

Known cobras

All members of the genus Naja, the "true" cobras, rear and produce hoods.

Other "cobra" genera and species are as follows:

The false water cobra, Hydrodynastes gigas, is the only "cobra" which is not a member of the Elapidae. It does not rear, produces only a slight flattening of the neck, and is only mildly venomous.
