Mexico's Jesus lizard got its name from an unusual ability to run over water on its hind legs, its body semi-erect and its front limbs dangling in the air. The spiny-tailed iguana and bearded dragon, ...

Researchers have uncovered multi-level relationships between locomotion - the ways animals move - and brain architecture, using high-definition 3D models of lizard and snake brains. Researchers at the ...

I HAVE recently observed bipedal locomotion (p. 551) in the case of Calotes versicolor similar circumstances to those noted by Mr. Ernest Green, and have reason to believe that it also occurs in the ...

When early tetrapods transitioned from water to land the way they breathed air underwent an evolutionary revolution. Fish use muscles in their head to pump water over their gills. The first land ...

Using biological experiments, robot models, and a geometric theory of locomotion, researchers investigate how and why intermediate lizard species, with their elongated bodies and short limbs, might ...
