Elapidae is a large family of highly venomous snakes, widely distributed across tropical and subtropical regions worldwide, including Asia, Africa, Australia, and the Americas.

All members of this family share key features: They have fixed, short hollow fangs at the front of the upper jaw (proteroglyphous dentition), used to inject fast-acting neurotoxic venom. Most species are slender with smooth scales, and many show bright warning coloration or iconic hood displays.

Famous species in the Elapidae family include:

Most Elapids rely on neurotoxic venom that attacks the nervous system, causing paralysis and respiratory failure. Unlike vipers (Viperidae), they usually do not have long hinged fangs, and their venom is more lethal in small doses.

Many species play critical roles in ecological balance, controlling rodent and reptile populations.
