Snakes are a diverse group of reptiles, having colonized almost every environment on the planet. Multiple snake lineages have independently evolved semiarboreal or completely arboreal species. As snakes lack limbs, the challenges of moving and feedin

Synopsis Snakes, with the obvious exception of the fangs, are considered to lack the regional specialization of tooth shape and function which are exemplified by mammals. Recent work in fishes has suggested that the definition of homodont and heterod

Prey-handling behavior serves as an important link between the processes of prey capture, transport, and swallowing. Snakes, lacking limbs, have developed a series of complex behaviors for the purposes of subjugating and handling their food. Using ca

The rapid strike of snakes has long been of interest in terms of mechanical performance. Recently, several nonvenomous taxa have been found to strike with the same incredible strike velocity and acceleration as the high-performing vipers. However, li

Plethodontid salamanders have a myriad of defense mechanisms with which to escape predation. One of the most poorly understood mechanisms is jumping, which is driven by lateral body bending; rapid straightening of the body propels the salamander into

The rapid strike of snakes has interested researchers for decades. Although most work has focused on the strike performance of vipers, recent work has shown that other snakes outside of the Viperidae can strike with the same velocities and accelerati

Unlike most terrestrial vertebrates, which use force generated from the hind limbs to jump, salamanders jump by laterally bending and then rapidly straightening the body, using momentum to carry the individual through the air. This movement is striki

Functional morphology and biomechanics seek to reveal the mechanistic bases of organismal functions and the physical principles involved at the phenotype-environment interface. Characterization of fluid flow (air or water) within and around organisma

SUMMARYBiotic factors such as body size and shape have long been known to influence kinematics in vertebrates. Movement in aquatic organisms can also be strongly affected by abiotic factors such as the viscosity of the medium. We examined the effects
