As venomous snakes go, the coral snake is a clumsy biter. Unlike pit vipers such as rattlesnakes and cottonmouths, which have gruesomely efficient fangs that articulate forward during a strike and inject venom like hypodermic needles, the brightly colored coral snake has small, rear-facing fangs that guide venom into a wound. This process doesn’t always work well — experts estimate that 25 percent of coral snake envenomations are dry bites — which is perhaps why the coral is so unaggressive. The snake is found throughout Florida, as well as in parts of Alabama, South Carolina, Louisiana, Texas and Arizona, but there are generally only about 100 or so bites each year.
What the coral lacks in belligerence, it makes up for in neurotoxicity. Unlike bites from pit vipers, which cause immense pain and swelling at the wound site, coral snake victims usually report little pain after being bitten. But the effects begin to show within hours, with symptoms such as tingling sensations in the extremities, dysarthria (slurred speech) and ptosis (droopy eyelids). Then a victim’s lungs shut down. “The venom acts as a neuromuscular blockade to the lungs,” University of Florida professor of medicine Craig Kitchens says. “Without antivenom, you need artificial respiration or you die.”
Unfortunately, after Oct. 31 of this year, there may be no commercially available antivenom (antivenin) left.
