Rectilinear locomotion relies upon two opposing muscles, the costocutaneous inferior and superior, which are present on every rib and connect the ribs to the skin. [5] [6] Although it was originally believed that the ribs moved in a "walking" pattern during rectilinear movement, studies have shown that the ribs themselves do not move, only the muscles and the skin move to produce forward ...
It then forms anterior grips and pulls the body forward, again demonstrating the 'path following' characteristic. Unlike tunnel concertina locomotion, this mode avoids any obstacle which falls between the bends of the snake's body. [5] However, it is exceptionally slow, with snakes rarely moving faster than 2% of their length per second. [5]
Many species of snake are highly arboreal, and some have evolved specialized musculature for this habitat. [13] While moving in arboreal habitats, snakes move slowly along bare branches using a specialized form of concertina locomotion , [ 14 ] but when secondary branches emerge from the branch being moved on, snakes use lateral undulation , a ...
Paddle-tailed sea snakes prey on fish eggs extracted from coral reef crevices. Some tree snakes have specialized jaws to extract snails from their shells, and use special chemicals to "de-slime" them.

Snakes primarily rely on undulatory locomotion to move through a wide range of environments. Undulatory locomotion is the type of motion characterized by wave-like movement patterns that act to propel an animal forward. Examples of this type of gait include crawling in snakes, or swimming in the lamprey. Although this is typically the type of ...
The ventral scales of sidewinding snakes are short and have small, microscopic holes in them to reduce friction, as opposed to the more spike-shaped ones of other snakes. These are more prominent in the African horned viper and sand vipers than the American sidewinder, theorised to do with the formers' environments being older by millions of years.
The warmer a rattlesnake, the faster it vibrates its tail. [6] Rattlesnakes tail-vibrate faster than other snakes, with some individuals nearing or exceeding 90 rattles per second. [7] [8] This makes rattlesnake tail vibration one of the fastest sustained vertebrate movements—faster than the wingbeat of a hummingbird. The movement is possible ...
