In concertina locomotion, blocks of muscles are activated simultaneously, and unilaterally, in regions of bending and of static contact with the sides of a tunnel. Rectilinear locomotion is movement in a straight line. It is used mainly by large snakes ...
WebAug 3, 1990 · 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 … WebJan 11, 2024 · Jayne said snakes typically climb steep, smooth branches or pipes using a movement called concertina locomotion in which the snake bends sideways to grip at least two regions.

WebJul 1, 2024 · In all types of concertina locomotion, the distance from the head to the tail changes substantially as snakes alternately flex and then extend different portions of their body. However, snakes climbing cylinders with concertina exert forces medially to attain a purchase on the branch, whereas tunnels require pushing laterally to form an ...
WebFor snakes, the choice of locomotor mode significantly affects locomotor energetics. For example, the energetic cost of concertina locomotion is seven times greater than that of lateral undulation (Walton et al. 1990).
