Abstract

 This study quantifies the morphometric relationship between total length (TL) and head length (HL) for a sample of 53 Mugger crocodiles (43–280 cm TL) in Iran. Across the size range of crocodiles sampled, the relationship was best described by a linear regression (TL= 15.52 + 6.283HL). The average TL/HL ratio was 7.034, which is similar to that reported for other crocodilian species and confirms its usefulness for estimating TL based on HL during population surveys.
