Statistics of regression analysis according to the equation organ mass=aBMb (masses in kg) for reptiles. (Allometric organ equations for birds and mammals are from Calder (1996); the data for gut contents of mammals from Clauss et al. (2007a) and for birds from Herd & Dawson (1984), Dawson et al. (1989) and Grajal (1995); n.a., not available.)
