Elapidae (with some exceptions)
All of the known cobras are venomous and many are capable of rearing upwards and producing a hood when threatened.
Snakes known as cobras
All members of the genus Naja, the "true" cobras, rear and produce hoods.
Other "cobra" genera and species are as follows:
- The rinkhals, or ring-necked spitting cobra, Hemachatus haemachatus, so called for its neck band as well as its habit of rearing and spreading its hood when disturbed
- The king cobra, Ophiophagus hannah
- The two species of tree cobra, Goldie's tree cobra and black tree cobra
- The two species of shieldnose cobras, Cape coral snake and Aspidelaps scutatus:p.76
- The two species of black desert cobra, desert black snake and Walterinnesia morgani, neither of which rears or produces a hood:p.65
- The so-called American cobra, the eastern coral snake, which also does not rear or produce a hood:p.30
The false water cobra, Hydrodynastes gigas, is the only "cobra" that is not a member of the Elapidae. It does not rear, produces only a slight flattening of the neck, and is only mildly venomous.:p.53

- Two non-venomous species of snake, the hognose snake and the striped keelback, also rear and produce hoods but are not considered "cobras"; likewise, some venomous elapid snakes such as the black mamba are also capable of producing hoods but are not called "cobras".
