There are 27 species of Old World coral snakes, in three genera (Calliophis, Hemibungarus, and Sinomicrurus), and 83 recognized species of New World coral snakes, in two genera (Micruroides and Micrurus).
Micrurus fulvius, commonly known as the eastern coral snake, [3] common coral snake, American cobra, [4] and more, is a species of highly venomous coral snake in the family Elapidae. The family also contains the cobras and sea snakes . [ 5 ]
Other nonvenomous snakes resemble the Texas coral snake as a form of Batesian mimicry. In the United States only, all three species of venomous coral snakes (Micruroides euryxanthus, Micrurus fulvius, and Micrurus tener) can be identified by the red rings contacting the yellow rings. A common mnemonic device is "red and yellow, kill a fellow.

The venom of M. lemniscatus is a potent post- and pre-synaptic neurotoxin, which causes a potent and irreversible neuromuscular block in vertebrates. [6] Lemnitoxin, a potent myotoxic PLA2 type toxin, isolated from the venom of M. lemniscatus induces local and systemic myotoxicity after intramuscular and intravenous injection in mice, which is antigenically related to Micrurus nigrocinctus ...
