Full Answer

The Naja genus includes the Arabian, Chinese, Sumatran, Egyptian, Monocled, Burrowing, Philippine, Caspian and Mozambique spitting cobras. Among the trademark features of these species is the ability to raise the forward portion of the body and to flatten the appearance of the neck when threatened. However, since a wide number of other species share these same features, they are commonly included as cobras. King cobras, mambas, adders, and taipans are just a few examples of snakes that are referred to as cobras but are not part of the Naja genus. Additionally, many sea snakes, including Kraits, also share these characteristics.

According to Live Science, all snakes classified as cobras are Elapids, meaning their fangs are hollow and affixed to the front top jaw. All varieties of cobra are highly poisonous and can be found throughout the world. The coral snake for example, another cobra relative, can even be found in the United States. In addition to other food sources, Elapids often demonstrate cannibalistic tendencies, feeding on other species of snakes. Indeed, fellow snakes make up the majority of the Krait's diet.
