Bites with a Arizona (Old World) coral snake are very rare and the majority reported bites are the response to people looking to handle the snake. Being smaller than average colorful, individuals are influenced to handle the "cute critter" to secure a closer look. That has to be a large mistake. Should you be bitten, seek immediate medical help. The results of the venomous toxin will surely have delayed reaction. As a "neurotoxin", it can slurred speech and diplopia and if enough venom is injected, you'll be able to cause serious respiratory consequences.
Arizona Coral Snake
As I've got other source about this Arizona coral snake in arizona-leisure.com, that Arizona coral snake can be referred to as the "western coral". The brightly colored coral snake is venomous and has a scary reputation, but is not as dangerous to humans being a rattlesnake. The coral relates to the cobra and ounce-for-ounce, its venom is twice as potent as that surrounding the Mohave Rattlesnake, considered the most venomous of rattlesnake species. However, there's never been a recorded fatality in the bite of your harlequin-snake.
Why is it? That's although its venom is deadly potent, the Arizona Coral includes a poor poison delivery system. It features a small mouth with small fangs that may hardly break our skin. It carries little venom and would need to hang-on and sustain a bite for a duration to inject enough venom to perform serious harm. At about 13 to 20 inches long for adult, this is a small snake. It is highly secretive, nocturnal and is not a hostile snake. It will always avoid human contact.
