Allometric scaling of body length was examined for 1,733 estimates of body length for a broad taxonomic and size range of mammals. Mammal species were classified by locomotion, habitat, and taxonomic relatedness. Scaling exponents found in different groups of mammals were compared to those predicted by geometric (0.333) and elastic (0.250) similitude models. The scaling exponent for the length: mass relationship 0.359 agreed better with the geometric-similitude model. However, the relationship between body length and body mass was not linear as previously postulated, and differences in the scaling exponent were found between marine and terrestrial mammals and between volant and non-volant forms. Allometric scaling of body length also varied among orders and families of mammals.
