10.1.1.Identification
The Crotalidae are called pit vipers because of the small, deep pits between the nostrils and the eyes (Fig. 9-2). They have two long hollow fangs, which normally are folded against the roof of the mouth, but which can be extended by a swivel mechanism when they strike. Other identifying features include thick bodies, slit-like pupils of the eyes, and flat triangular heads. Further identification is provided by examining the wound for signs of fang entry in the bite pattern shown (Fig.1). Individual identifying characteristics include audible rattles on the tails of most rattlesnakes and the cotton white interior of the mouths of moccasins.

Coral snakes are related to the cobras, kraits, and mamba snakes in all areas of the world (Fig.2). Corals, are comparatively thin snakes with small bands of red, black, and yellow (or almost white). Other nonpoisonous snakes have the same coloring, but in the coral snake, the red band always touches the yellow band. Its short, grooved fangs must chew (bite pattern Fig. 2) into its victim before the poison can be introduced.
