In nature, salamanders adapted to terrestrial and aquatic environments as well as varying substrate conditions in their habitats. Discovering more about the effects of substrate types on the kinematic measurements of underwater walking can offer us with more information regarding biological principles and limb evolution. A previous study conducted on the same salamander subjects led us to believe that a rough substrate such as gravel will provide the salamander with better traction and grip to thrust forward for walking underwater compared to a smooth substrate. Therefore, a rougher substrate is expected to have resulting kinematics that will differ significantly from …

The transition from aquatic to terrestrial locomotion was a landmark event in the evolutionary history of vertebrates. In order to better understand how early tetrapods were able to transition to land, salamanders have proven to be a useful animal model. With current research focusing heavily on the anatomy, physiology, and kinematics defining salamander terrestrial walking capabilities, this experiment was designed to extract information about the kinematics of salamander walking underwater. Underwater walking of salamanders was analyzed on smooth and rough substrates to provide more insight into the early vertebrate water-to-land transition. Average salamander stride duration, time in stance phase, time …
