Weight-Length Relationships in Thirteen Species of Snakes in the Southeastern United States

Glennis A. Kaufman and J. Whitfield Gibbons



Regression equations of the form y = axb were calculated for the relationship between body weight (y) and snout-vent length (x) in 13 species of snakes from the southeastern United States.  All species except two (Crotalus horridus and Heterodon platyrhinos) had slopes which were not significantly different from 3.00.  The effect of season on weight-length relationships was examined in four species and found to be a significant factor in one (Natrix sipedon).  Sex was found to have a significant effect on the relationship in only two species, C. horridus and Coluber constrictor.  Tail ratios (tail length/total length) were greater in males than in females for adults of all species.  The percentage of the sample with broken tails in each species was positively correlated with the mean tail ration for each species.
