Texas Poisonous (Venomous) Snakes
Snakes! Are they sneaky, slimy, scary?...or...skillful
and simply sensational? People either love 'em or hate 'em, but either way,
snakes play an important role in our world!
are reptiles. Reptiles are cold-blooded so they must warm themselves in the
sun or on rocks. Snakes have skin covered with scales and most lay eggs. Some
snakes hold their eggs inside until they hatch.
Snakes have no legs and no ears.
Snakes are skilled predators.
How would you catch prey without
arms or legs? Venomous snakes have poison
to inject in their prey. The venom keeps small prey still so the snake can
grab it with its
mouth and swallow it whole. This is a helpful adaptation for snakes. Snakes
help the balance of nature by eating prey that reproduces frequently, everything
from earthworms to rabbits. Snakes also eat eggs. Snakes are especially important
in the control of mice and rats.
Venomous Snakes in Texas
There are four kinds of venomous snakes in Texas: coral snakes, copperheads,
cottonmouths (water moccasins) and rattlesnakes.
Only one species of coral snake is native to Texas. The coral snake is shy
and rarely seen. It has, in order, red, yellow and black colors.
The coral snake has a small mouth, and is usually not aggressive. Its bites
are dangerous, but very rare.
harmless snakes have similar colors in a different order. The rhyme "red
and yellow kill a fellow" can help you remember that the coral snake's
red and yellow colors touch, but the harmless milk snake has red touching
What is a Pit Viper?
A pit viper is a type of venomous snake. Copperheads, cottonmouths and rattlesnakes
are called pit-vipers because they have a pit near each nostril which is highly
sensitive to heat. This pit helps the snake in locating warm-blooded prey.
Copperhead snakes have bands of gray and/or brown with a copper-colored heard.
They blend in with
leaf-covered forest floors and it's possible to stare right at a copperhead
without seeing it! Copperheads bite rather than strike. Because they are
so well camouflaged, most bites occur when a snake is accidentally picked up
or sat or laid on. Always use care when picking up or flipping over logs, boards,
old tin or other items where copperheads may be resting.
The cottonmouth, or water moccasin, rarely strays far from water. It can
be found in marshes, swamps, ponds, lakes, ditches, and canals in East and Central
Texas and along the Gulf coast. It is a stubby, muscular snake and can grow
to nearly six feet. When threatened, it will open its mouth to show its
fangs. The inside of its mouth is white and reminded people of cotton, hence
the name cottonmouth. They eat frogs, fish an small animals. These snakes can
be very defensive and sometimes aggressive. They can
bite underwater. Swimmers, bathers and anglers on
river banks should always keep an eye open for these snakes.
The Western Massasauga lives in prairies from the Gulf Coast up to the Panhandle
The Timber Rattlesnake lives in East Texas.
Western Diamondback lives in North, Central, South and West Texas.
Nine kinds of rattlesnakes are found in Texas, including the massasauga. Rattlesnakes
usually "rattle" before striking, but if they are totally surprised,
they may strike before rattling. Most of the rattlesnakes are active at night,
when they hunt for prey such as mice, rats and rabbits.
Preventing Snake Bites
Watch where you step, put your hands, or sit down. Venomous snakes live
on or near the ground. They lay on rocks, wood piles and other spots
for a place to sun and a place to hide. Snakes avoid your huge
body, but will definitely bite if stepped on or feel trapped. Most bites
happen around the ankle and about 99% of all bites occur below the
knee, except when someone accidentally picks up or falls on the snake.
The fangs of venomous snakes are long and sharp but they break easily. These
fangs usually don't penetrate canvas tennis shoes and almost never penetrate
leather shoes or boots. Watch carefully where you step, and wear boots in
tall grass to prevent most snake bites. If you or a friend get bitten, you
need to get to a hospital immediately.
Snakes are not something to be feared, but rather a creature to be respected
as a fascinating and helpful member of the outdoors.
