Poison gland Poison duct Fang (foofhj. alligators and crocodiles, and tuxtles. Our poisonous snakes. The feeling of horror that snakes arouse in some people is unreasonable. As a child you may have seen your elders shrink at the sight of a snake and you may have learned to imitate them. Children left to them- selves have no more fear of snakes than of any other animals that seem strange. Most snakes are harmless; poisonous snakes are the exception. In this country there are only four kinds of poisonous snakes: the rattlesnake, the copperhead, the water moccasin, and the coral snake. On our continent man is rarely bitten, even where poisonous snakes are nu- merous, for with the exception of the water moccasin our poisonous snakes are timid; they do not attack unless they are disturbed. Still more rarely does any one die of the bite. An understanding of the methods of treating a bite and the Gland-squeezing muscle 'y- Jaw-opening muscle courage to remain calm almost always prevent serious results from the poison. The poison is injected through a pair of large, hollow, very sharp fangs (teeth). These are in the upper jaw, folded back out of the way until the snake strikes. The swiftly-moving little tongue contains no poison; the snake uses it to learn of its surroundings. Rattlesnakes are widely scattered over the United States. When disturbed, they sound their rattles, which are located at the tip of the tail, so that it is easy to avoid them. It is only when they are taken by surprise that they strike with- out warning. The amount of poison in- jected depends on the size of the snake. Large rattlers are therefore more dan- gerous than small ones. The copperhead is found in various regions in the north- ern half of the country. The water moccasin and the coral snake are not. Please note that these images ar
