Also known as the "western coral". The brightly colored coral snake is
venomous and has a scary reputation, but is not as dangerous to humans
as a rattlesnake. The coral is related to the cobra and ounce-for-ounce, its
venom is twice as potent as that of the Mohave Rattlesnake, considered
the most venomous of rattlesnake species. However, there has never
been a recorded human death from the bite of a coral snake.
Here's Why
Although its venom is deadly potent, the Arizona Coral has a poor poison
delivery system. It has a small
mouth with small fangs that can hardly
break human skin. It carries little venom and would have to hang-on and
sustain a bite for a duration to inject enough venom to do serious harm.
At about 13 to 20 inches long as an adult, it is a small snake. It is highly
secretive, nocturnal and is not an aggressive snake. It will always avoid
human contact.
Bites by a coral snake are very rare and most reported bites are the result
of people trying to handle the snake. Being small and brightly colored, people
are tempted to handle the "cute critter" to get a closer look. That would be
a big mistake. If you are bitten, seek immediate medical help. The effects
of the venomous toxin can have delayed reaction. As a "neurotoxin", it can
cause slurred speech and double vision and if enough venom is injected, it
is possible to cause serious respiratory consequences.
Characteristics of the Coral Snake
The adult coral snake is small. Its average length is 13 to 20 inches long and
has brightly colored bands of black, red and yellow that encircle the body of
the coral. The Scarlet King Snake, with very similar banded color is often
mistaken as a coral snake. The king snake is not venomous and poses no danger
to people. At an average adult length of 48 to 72 inches long, the king snake
is much longer than the venomous coral.
Here's a good way to identify the coral other than size. The coral's red bands
that encircle its body touch the yellow bands that also encircle its body. It has
a blunt nose and its head is completely black. However, it is never wise to
handle a snake unless you are absolutely sure it is not venomous. Observing
wildlife is a privilege, but never harass or do harm to any wildlife.
Coral Snake Behavior and Habitat
As described above, Arizona Coral Snakes are small, shy and reclusive. Although
there are exceptions, most bites only occur when the snake is handled. Coral
snakes hunt by night and prefer a diet of smaller ground snakes and lizards. Their
venom acts quickly upon these smaller cold-blooded creatures causing fast
paralysis and respiratory failure. Coral snakes typically lay two to three eggs by
the end of summer. After approximately ten weeks, the young snakes hatch.
Western coral snakes live in Arizona's and northern Mexico's Sonoran Desert. They
are often found in rocky locales where Saguaro cacti are present. They prefer the
cool microcosm of life under rocks where they are not likely to encounter much
company. They may even bury themselves in sand or soil. Because they are nocturnal
creatures, they are seldom seen in the wild. If they are seen during daylight, it is
usually during overcast days or after daytime rain.
