You don't have to be a
Kardashian to stand out on the Internet — all you need is at least 20 pairs of
bright-yellow legs, a gleaming red head and venomous fangs.
Last week, the Texas Parks and Wildlife
Department (TPWD) posted a picture of a giant redheaded centipede to its social media pages that met all
of the above criteria. The image quickly went viral. While many people reacted
with horror (apparently, giant, colorful centipedes are the stuff of
nightmares), this critter doesn't eat people or seriously harm them in any way
(at least not usually).
However, giant redheaded centipedes (Scolopendra
heros) — which can be found in certain regions of the southern
United States and northern Mexico — do take people by surprise fairly often,
said Ben Hutchins, an invertebrate biologist with the TPWD. [Gallery: Out-of-This-World Images of Insects]
In a 2014 article published in TP&W magazine, Hutchins explained that S. heros typically
hangs out under rocks, logs or leaves. But sometimes, these centipedeswander
into people's homes, where they can cause panic, thanks to their 8-inch-long
(20 centimeters) bodies and dozens of legs (they typically have 21 to 23
pairs). The critters use their many appendages to grasp prey while feeding.
Though S. heros mainly munches on invertebrates
like insects and arachnids, the impressively sized centipede is also known to
take down larger prey, such as rodents, snakes, lizards, toads and other small
vertebrates. In captivity, giant redheaded centipedes seem to prefer eating
moths, according to the
University of Arkansas Arthropod Museum.
The critter kills its victims using its "fangs,"
or forcipules, which are located near its mouth and contain venom glands that
inject a toxin into its unlucky prey. The giant redheaded centipede is also
thought to inject venom into prey with its many legs, which can make tiny
incisions in human skin, according to the Arthropod Museum.
When
one of these giant creepy-crawlies bites a human, the result is usually pretty
painful, according to both the Arthropod Museum and Hutchins. Victims of these
centipede bites report localized pain and swelling, but Hutchins said people
also have reported skin necrosis (tissue death), dizziness, nausea and
headaches, Hutchins wrote in his article.
Hutchins also lists muscle tissue damage, kidney
failure and heart attack as rare side effects of the centipede's nibble. A case
report published in
2006 in the Emergency Medical Journal cites a bite from a centipede, likely
of the genus Scolopendra,
as the cause of acute myocardial infarction (heart attack) in an otherwise
healthy 20-year-old man. Whether a giant redheaded centipede was responsible
for that unfortunate event isn't stated in the report.
Should you happen upon one of these giant centipedes,
pay attention to its colorful body parts. Known as aposematic coloration, or
warning coloration, the critter's bright colors serve to warn predators that,
while S. heros might
look tasty, it's really a poisonous treat. Consider yourself warned.
