By Theydiffer - January 14, 2016

If you see a snake in your backyard or elsewhere near the place you live, the best advice is not to look for telltale signs of a venomous snake, but just leave it alone, and call the animal control service responsible for handling snakes in your area. For other purposes, we will discuss the differences between the two types of snakes in this article.

  • Contrary to popular belief, all snakes have tails. That is, the head is a separate organ from the tail. The tail of non- venomous snakes has a double row of scales on the end of the tail (from the anus to the very end.) There is a visible line that separates the two rows. Venomous snakes, on the other hand, have a single row of scales on the end of the tail. If you do not see the line separating two rows of scales, this is a telltale sign that a snake is poisonous.
If the underside of a snake has a single row of scales, the snake is most probably venomous. Likewise, if the tail plates are in double plates, the snake is likely to be non-venomous.

  • Venomous snakes have heat sensing pits that work like a heat detector to identify the whereabouts of a prey. Heat sensing tips are situated between the eye and the nostril of the snake. Some non-venomous snakes also have a heat sensing pit, but most do not.
Heat sensing pits are telltale signs of a venomous snake.
