...Keegan Lutek; Kathleen L. Foster; Emily M. Standen ABSTRACT Amphibious fishes moving from water to land experience continuous changes in environmental forces. How these subtle changes impact behavioural transitions cannot be resolved by comparisons of aquatic and terrestrial locomotion. For example...

... across the actinopterygian tree. To compare locomotor mode between species, we mapped biomechanical traits on an established amphibious fish phylogeny. Although the diversity of fish that can move over land is large, we noted several patterns, including the rarity of morphological and locomotor...

These observations may be a further example of adaptive plasticity in Polypterus , allowing for greater bursts of power during terrestrial locomotion.
