Cobra

While the members of the genus Naja constitute the true cobras, the name cobra is also applied to these other genera and species:

• The rinkhals, ringhals or ring-necked spitting cobra (Hemachatus haemachatus) so-called for its neck band as well as its habit of rearing upwards and producing a hood when threatened^[2]
• The king cobra or hamadryad (Ophiophagus hannah)^[3]
• The two species of tree cobras, Goldie's tree cobra (Pseudohaje goldii) and the black tree cobra (Pseudohaje nigra)^[4]
• The two species of shield-nosed cobras, the Cape coral snake (Aspidelaps lubricus) and the shield-nosed cobra (Aspidelaps scutatus)^[4]: p.76
• The two species of black desert cobras or desert black snakes, Walterinnesia aegyptia and Walterinnesia morgani, neither of which rears upwards and produces a hood when threatened^[4]: p.65
• The eastern coral snake or American cobra (Micrurus fulvius), which also does not rear upwards and produce a hood when threatened^[4]: p.30

The false water cobra (Hydrodynastes gigas) is the only "cobra" species that is not a member of the Elapidae. It does not rear upwards, produces only a slight flattening of the neck when threatened, and is only mildly venomous.^[4]: p.53
