Regression analysis between body and head measurements of Chinese alligators (Alligator sinensis) in the captive population
Four body-size and fourteen head-size measurements were taken from each Chinese alligator (Alligator sinensis) according to the measurements adapted from Verdade. Regression equations between body-size and head-size variables were presented to predict body size from head dimension. The coefficients...

The coefficients of determination of captive animals concerning body- and head-size variables can be considered extremely high, which means most of the head-size variables studied can be useful for predicting body length. The result of multivariate allometric analysis indicated that the head elongates as in most other species of crocodilians.
