Snakes are probably the most feared and misunderstood animals known. There are over 200 species of snakes in the U. S., most of which (about 170) are non-venomous. Utah is home to 31 species of snakes. Of these, 24 are non-venomous. Since these snakes are more abundant, chances are that when most Utahns encounter a snake it will be non-venomous. (See Figure 1.)
