Among the venomous snakes belonging to the family Elapidae, order Lacertidae, this is a snake that can hold the front of its body upright and spread its ribs to expand its neck. It is generally large in size, usually lives on the ground, and is active and aggressive. It has a pair of venomous fangs with deep grooves at the front end of its upper jaw, and the venom flows through the grooves and enters the body of the victim it bites. The venom is a neurotoxin that has the effect of paralyzing the respiratory center. Many species can spit venom at their enemies, and this ability is particularly notable in the spitting cobra Hemachatus haemachatus and the black-necked cobra Naja nigricollis . They are found in tropical and subtropical regions of Asia and Africa. One of the most famous species is the Indian cobra, and its local type can also be found in Taiwan.
