Most people dislike rattlesnakes. Years ago people commonly believed that these and other snakes had the power to cast a spell on people. Some people become almost terrified at the thought of even seeing a rattler. Even the lover of the outdoors is compelled to. look out for these creatures. However, a few sensible precautions decrease the chances of being struck by any poisonous snake.
Rattlers come in a variety of sizes—from about two feet in length to over six feet. At the end of the rattler’ s tail it is a set of rings. These make up the rattle. When the snake is alarmed, the tail shakes, causing a warning noise to be transmitted a considerable distance.
Rattlers may be found in nearly all states and in some Canadian provinces. However, most of them arc more at home in dry places, such as the western United States and Mexico. Rocky, isolated areas are favorite places for rattlers to lodge. They may be seen mornings and evenings sunning on rocky ledges. In the heat of the day they seek out a shelter from the sun under rocks or in holes.
The rattlesnake is in some ways a friend to humans. This statement contradicts some common views of these creatures. The harmful poisonous fluid released in a rattler’ s bite kills small animals—and may kill or cause sickness in people. However, rattlers are competitors with owls and hawks for mice and rats. Many of these pests have been the losers in a clash with a rattlesnake in its quest for food. Thus the rattler helps control the numbers of mice and rats.
How can you avoid a rattlesnake bite.’? A few principles have been given by experienced people of the outdoors. First, do not run through high grass in rattlesnake country. You might surprise a snake that is otherwise minding its own business. A slow walk insures ample time for the snake to slide away or proclaim its presence.
Although these snakes are very mobile, they will not chase you. If you hear a rattle, back up and walk away slowly. Do not run ! The snake may have a friend or relative in the area who would resent being stepped on as you dash away.
Second, consider your wearing apparel, particularly footwear. Snake fangs have occasionally pierced thick, western boots. However, such footwear offers much more protection than the usual shoes.
Finally, when chimbing, look before you reach or step. Rattlers like to lie on rocky ledges. Although you intended to grab a rock rather than a rattler, the surprised snake may not understand.
The following statements are true EXCEPT ______.
