| β 0+β mass | 5.8 | 4.99, 6.58 | 0.71 | 0.10 | |
| β 0 | 5.5 | 4.78, 6.28 | 0.64 | NA | |
| Maximum | β 0+β mass x β environment | 0.0 | NA | 0.48 | 0.28 |
| β 0+β mass | 0.9 | 0.04, 2.07 | 0.74 | 0.23 | |
| β 0 | 4.8 | 4.23, 5.29 | 0.57 | NA | |
| Range | β 0+β mass x β environment | 0.0 | NA | 0.30 | 0.28 |
| β 0+β mass | 1.6 | 0.23, 3.1 | 0.73 | 0.23 | |

Results are from phylogenetic least squares (PGLS) regression analyses computed for 1000 alternative resolutions of the mammalian phylogeny. Model terms include carnivore body mass (β mass), environment either aquatic or terrestrial (β environment) and the intercept (β 0).
