Figure Relationships between snout-vent length and 2 measures of interfang distance for southern California rattlesnakes (genus Crotalus): distance between the midline of the fang sheaths (fang bases) measured in anesthetized snakes, and distance between fang marks in a plastic membrane from a defensive bite obtained during a venom extraction (fang punctures). Data are pooled for the 2 sexes and 5 species tested due to statistical similarity. 95% CI are illustrated. See text for regression equations (Equations 1 and 2). n = 79 snakes.
