TABLE 1. — Regression equations used to estimate body mass (in kg, unless noted otherwise) from body lengths for turtles and crocodylians.

Taxon	Measurement, x (cm)	Regression to body mass	Regression source
Testudinidae	Carapace length	BM = 2.751*log10(x) -3.424	Regression derived from data in Regis & Meik (2017)
Trionychidae	Carapace length	log10(BM) = 1.344*log10(x) -1.049	Regression derived from data in Regis & Meik (2017)
Pelomedusidae	Carapace length	log10(BM) = -3.814 + 2.861*log10(x)	Regression derived from data in Regis & Meik (2017)
Crocodylia	Total length	log10(BM) = -4.67 + 2.79*log10(x)	Slavenko et al. (2016)
Python	Total length	log10(BM) = -5.131 + 2.611*log10(x) [mass unit: g]	Feldman & Meiri (2013)
