... species means, fCSA scaled more steeply in invertebrates (∝ M b 0.575 ), fish (∝ M b 0.347 ) and other reptiles (∝ M b 0.308 ) compared with varanids (∝ M b 0.267 ), which had a slightly higher scaling exponent than birds (∝ M b 0.134 ) and mammals (∝ M b 0.122 ). This suggests that, while fCSA generally...
