Although some species of venomous and mildly venomous snakes do use constriction to subdue their prey, most snakes which use constriction lack venom. [1] The snake strikes at its prey and holds on, pulling the prey into its coils or, in the case of very large prey, pulling itself onto the prey. The snake then wraps one or two loops around the ...
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 ...
Concertina movement is the method by which a snake or other organism anchors itself with sections of itself and pulls or pushes with other sections to move in the direction it wants to go. To spring forward a snake may require a rough surface to thrust back against. [1] [2] It is named after the concertina musical instrument. [citation needed]

At least one species uses constriction to subdue its prey, [10] [11] which include elongate vertebrates: reptiles (snakes), amphibians (caecilians), and fish (eels). [ 10 ] [ 12 ] Prey are swallowed from one end using rotational movements of the braincase and mandibles, a process that takes up to 30 minutes for larger prey. [ 13 ]
Another common snake species in Washington is the gopher snake, which kills its prey by constricting it. At three- to four-foot long, this snake is often mistaken for a rattlesnake because of its ...
Rarely do individuals lack both the ventral and neck band coloration, so the use of those two characteristics is the simplest way to distinguish the species. [6] Size also varies across the species' distribution. Typically, adults measure 25–38 cm (10–15 in) in length, [6] except for D. p. regalis, which measures 38–46 cm (15–18 in). [7]
