Implication

Comparative review reveals diverse feeding kinematics and motor control strategies across amphibians, indicating that movement stereotypy is an exception driven by specific biomechanical constraints.

Key Points

To examine the diversity and evolutionary trajectories of motor control and feeding kinematics across amphibian lineages.
Reviewed comparative kinematic and biomechanical data on feeding behaviors across diverse frog and salamander taxa.
Evaluated evolutionary patterns of motor control, focusing on feedback/feed-forward modulation and tongue-jaw coordination.
Amphibian feeding is not universally stereotyped; lineages have diverged into either increased motor modulation or mechanically constrained coordination.
Ballistic-tongued frogs exhibit reduced targeting accuracy due to demanding multi-joint coordination between jaws and tongue, whereas decoupling these movements in salamanders and hydrostatic-tongued frogs enhances accuracy.
