The net energetic cost of terrestrial locomotion by the snake Coluber constrictor, moving by lateral undulation, is equivalent to the net energetic cost of running by limbed animals (arthropods, lizards, birds, and mammals) of similar size. In contrast to lateral undulation and limbed locomotion, concertina locomotion by Coluber is more energetically expensive. The findings do not support the widely held notion that the energetic cost of terrestrial locomotion by limbless animals is less than… 
Aquatic and Terrestrial Locomotory Energetics in a Toad and a Turtle: A Search for Generalisations among Ectotherms*
Comparing the cost of transport, the energy required to transport a mass of animal over a unit distance, with other animals showed that toads do not have a cheap form of terrestrial locomotion, but turtles do; turtles use half the cost predicted from their body mass.
Limbless terrestrial animals propel themselves by sliding their bellies along the ground. Although the study of dry solid-solid friction is a classical subject, the mechanisms underlying
Snake-like locomotion: integration of geometry and kineto-statics
This paper deals with snake-like locomotion that is distinguished from wheeled and legged locomotion by fundamental physical differences, and proposes a biologically motivated alternative locomotion for mobile robots.
Crawling without wiggling: muscular mechanisms and kinematics of rectilinear locomotion in boa constrictors
Unlike most limbless vertebrates, snakes can propel themselves without bending their long axis because of muscles that both move the skin relative to the underlying skeleton and modulate skin stiffness.

This work proposes recognizing five and four distinct types of lateral undulation and concertina, respectively, resulting in a total of 11 distinct gaits previously recognized as only four, partly as a result of different motor patterns.
A 'sidewinding' locomotion gait for hyper-redundant robots
The kinematics of a form of hyper-redundant mobile robot locomotion which is analogous to the sidewinding locomotion of desert snakes are considered and algorithms are developed which enable travel in a uniform direction as well as changes in direction.
Snake robot locomotion in narrow space: a review
In snake robot research, one of the most efficient forms of locomotion is the lateral undulation. However, lateral undulation, also known as serpentine locomotion, is illsuited for narrow spaces, as
Introduction to biotribology: Animal locomotion
Limbs of vertebrate animals have synovial joints, which enable the fish to lock the spine in the erect position, and the feet of insects and geckos adhere to solid surfaces, enabling these animals to climb vertical walls and even to walk on ceilings.
Bioenergetic and kinematic consequences of limblessness in larval Diptera.
The cost of transport in fly larvae is among the highest recorded for terrestrial locomotion, confirming the suggestion that biomechanical and kinematic properties of limbless organisms with hydraulic skeletons lead to very high costs of transport.

Energetics and mechanics of terrestrial locomotion. I. Metabolic energy consumption as a function of speed and body size in birds and mammals.
This series of four papers investigates the link between the energetics and the mechanics of terrestrial locomotion using data from 62 avian and mammalian species to formulate a new allometric equation relating mass-specific rates of oxygen consumed during locomotion at a constant speed to speed and body mass.

The muscular cycle of a snake exhibiting ‘crotaline’, or side-winding, movements is essentially the same as that during serpentine motion; the difference in the type of movement relative to the ground is due to a different in the nature of the external resistances offered by the animal9s environment.

This chapter discusses the evolution of Arthropod Locomotion as seen Through a "Vertebrate" Eye, as well as the role of Muscle in Insect Posture andLocomotion and the influence of exercise.
The aerobic cost of saltatory locomotion in the fowler's toad (Bufo woodhousei fowleri).
It is suggested that hopping in toads, as in small mammals, is not economical during sustained locomotion and is most important during short bursts of high-intensity activity.

The pattern and rate of limb loss are investigated by reviewing data from paleontology and comparative morphology, and theories of the reexpression of limb structures lost in mammalian evolution are considered in the light of facts from paleozoology and genetics.

Theoretical considerations combined with observed differences suggest that the more elongate body of Elaphe is advantageous for performing concertina locomotion, and there was no consistent evidence that nonhomologous muscles with tendinous interconnections functioned as single units during either of these two locomotor modes.
