Snakes can exhibit 5 different modes of terrestrial locomotion: (1) lateral undulation, (2) sidewinding, (3) concertina, (4) rectilinear, and (5) slide-pushing. Lateral undulation closely resembles the simple undulatory motion observed in many other animals such as in lizards, eels and fish, in which waves of lateral bending propagate down the ...
Sidewinding is a type of locomotion unique to snakes, used to move across loose or slippery substrates. It is most often used by the Saharan horned viper, Cerastes cerastes , the Mojave sidewinder rattlesnake , Crotalus cerastes , and the Namib desert sidewinding adder, Bitis peringueyi , to move across loose desert sands, and also by ...
This mode of concertina, while still slower than lateral undulation or sidewinding, is still fairly fast, with snakes moving approximately 10% of their length per second. [3] However, because the snake is straightening and re-forming bends, it requires the entire space of the tunnel to move, and any obstruction will disrupt locomotion.
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 ...

Have you ever been out walking your dog and thought, 'Why does my dog walk sideways?' It’s not an uncommon query; as a vet, it’s something I’ve seen a few times.

Each scale has an outer surface and an inner surface. The skin from the inner surface hinges back and forms a free area which overlaps the base of the next scale which emerges below this scale. [8] A snake hatches with a fixed number of scales. The scales do not increase in number as the snake matures nor do they reduce in number over time.
