About: Sidewinding

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

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 Homalopsine snakes in Southeast Asia to move across tidal mud flats. Any number of caenophidian snakes can be induced to sidewind on smooth surfaces, though the difficulty in getting them to do so and their proficiency at it vary greatly.

dbo:abstract
  • Das Seitenwinden ist eine spezielle Fortbewegungsweise, die vor allem bei den Schlangen zu beobachten ist. Dabei bewegen sich diese seitwärts über den Sand, indem sie sich immer an zwei Punkten mit dem gesamten Körper abrollen. Dabei wird der Kopf aufgesetzt und abgerollt, ihm folgt der gesamte Körper nach, während der Kopf bereits an einer neuen Stelle aufsetzt. Bei dieser Art der Fortbewegung berührt die Schlange nur mit einem kleinen Teil der Körperoberfläche den Boden. Es entstehen arttypische, J-förmige Spuren im Sand, deren Längsachsen zur Fortbewegungsrichtung einen spitzen Winkel bilden. Anzutreffen ist das Seitenwinden als Hauptfortbewegungsform nur bei wenigen in Wüsten lebenden Arten, denen es so möglich ist, sich effektiv über den feinkörnigen Sand zu bewegen. Dabei handelt es sich vor allem um die Seitenwinder-Klapperschlange (Crotalus cerastes) in Nordamerika, die Zwergpuffotter (Bitis peringueyi) in der westafrikanischen Namib sowie die Afrikanischen Hornvipern (Cerastes) im Norden Afrikas und der Arabischen Halbinsel.

  • 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 Homalopsine snakes in Southeast Asia to move across tidal mud flats. Any number of caenophidian snakes can be induced to sidewind on smooth surfaces, though the difficulty in getting them to do so and their proficiency at it vary greatly. The method of movement is derived from lateral undulation, and is very similar, in spite of appearances. A picture of a snake performing lateral undulation would show something like a sine wave, with straight segments of the body having either a positive or negative slope. Sidewinding is accomplished by undulating vertically as well as laterally, with the head tracing out an ellipse in a vertical plane nearly perpendicular to the direction of movement and with all the segments that have a significantly non-zero slope (and alternating segments that have a zero slope) lifted off the ground. 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 then the American Sidewinder, theorised to do with the former's environment being older by millions of years. In the resultant movement, the snake's body is always in static (as opposed to sliding) contact when touching the ground. The head seems to be "thrown" forward, and the body follows, being lifted from the prior position and moved forward to lie on the ground ahead of where it was originally. Meanwhile, the head is being thrown forward again. In this way, the snake slowly progresses at an angle, leaving a series of mostly straight, J-shaped tracks. Because the snake's body is in static contact with the ground, without slip, imprints of the belly scales can be seen in the tracks, and each track is almost exactly as long as the snake. Sidewinder rattlesnakes can use sidewinding to ascend sandy slopes by increasing the portion of the body in contact with the sand to match the reduced yielding force of the inclined sand, allowing them to ascend up to the maximum possible sand slope without slip. Implementing this control scheme in a snakebot capable of sidewinding allowed the robot to replicate the success of the snakes. One can determine the line of movement of the snake by drawing a line connecting either the right or left tips of the tracks. (en)
  • 蛇行,指的是蛇類生物在進行陸地移動時的主要方式。蛇類生物沒有足部,而是利用腹鱗及肌肉的縮放產生移動力。蛇的移動方式主要有四種,分別是蜿蜒式、側行式、直蠕式和風琴式。 (zh)
