Coral Snakes

PARENT PAGE

The cobra family (which includes coral snakes) contains some of the world's most dangerous snakes including cobras, mambas and sea snakes.  They're found worldwide and are the predominant family in Australia.  Only three species are found in North America -- two species of coral snakes and one sea snake (listed below).  Be sure to check the listing by state, too.

These snakes possess long, slender bodies and large scales (plates) on the head.  The small fangs in the front of the mouth are "effectively tubular" meaning they contain grooves that are enclosed by an in-folding of the tooth edges.

The coral snakes are relatively small snakes that spend most of their time underground.  Their primary food is other snakes.  Despite their small size and small fangs, their venom is extremely toxic.

Recently deceased snakes can still have a bite reflex.  Additionally, the poisons from these animals can still affect you long after they've been dead should you snag your skin on a fang for example.

As with all animals, these creatures are a normal and desired part of the ecosystem.  Seeing one should be considered a real treat and not an opportunity to molest it or kill it.

 

Identifying These Three Snakes

To differentiate the deadly coral snakes from harmless snakes having similar color, remember the simple rhyme...

"Red on black, friend to Jack."

"Red on yellow, kill a fellow."

Signs and Symptoms of Coral Snake Bites

After a bite from a coral snake, there may be no manifestations or systemic effects for as long as 12-24 hours.  However, signs and symptoms often develop after 1-8 hours.  These include:

  • A semi-circular pattern of teeth marks in the skin indicates a bite.  However, the bite may just break the skin's surface in the form of a small scratch or abrasion.

  • Localized numbness, weakness, and drowsiness

  • Ataxia -- an inability to coordinate muscle movements.

  • Slurred speech and excessive salivation

  • Low blood pressure

 

  • Drooping of the eyelids, double vision and dilated pupils

  • Abdominal pain

  • Nausea and vomiting

  • Paralysis of the tongue and larynx (produces difficulty breathing and swallowing)

  • Loss of consciousness

  • Seizures

  • Respiratory failure
