Genus Naja
Species N. naja

Naja is a genus of venomous elapid snakes. Although several other genera share the common name, Naja species are the most recognized and most widespread group of snakes commonly known as cobras. The genus Naja consists of 20 to 22 species, but has undergone several taxonomic revisions in recent years, so sources vary greatly.

Etymology

The origin of this genus name is from the Old Indic nāga, cognate with English 'snake', Germanic: *snēk-a-, Proto-IE: *(s)nēg-o-.

Description

Different Naja species vary in length and most are relatively slender-bodied snakes. Most species are capable of attaining lengths of 1.84 m (6.0 ft). Maximum lengths for some of the larger species of cobra are around 3.1 m (10 ft), with the forest cobra arguably being the longest species. All have a characteristic ability to raise the front quarters of their bodies off the ground and flatten their necks to appear larger to a potential predator.
