The 12 Most Commonly Dragged Animals

Some of the most common crawling animals are snakes, worms, leeches, earthworms or scorpions. Dragging is the movement characteristic of most reptiles and amphibians.

Insects also tend to crawl when they do not fly; Terrestrial molluscs such as snails and slugs crawl on a specialized foot for this.

Creeping animals

Most of the creeping animals do so because of their lack of appendages; Must use their bodies to generate a propelling force.

Salamanders crawl, as well as frogs and toads when they are not jumping. The lizards crawl with a characteristic movement from side to side that is replicated by their relatives: the snakes.

Most terrestrial invertebrates crawl, including flying species such as flies, moths and bees. These animals opt for a movement on their 6 legs to effectively move across the surfaces.

Some animals crawl at various stages of their life, but not at all. Humans, for example, crawl in their childhood and can revert to crawl on all four legs when the situation warrants it.

However, it is not an efficient way to move compared to the normal and still posture of adults.

Many land animals have other ways of moving apart from the dragged. An example of this are the riding of horses or the bipedal walk of humans; In spite of this crawling in four, six or eight legs is common.

Some animals can also form a ball and roll, as in the case of pangolin.

Common crawling animals

Snakes

The 12 Most Commonly Dragged Animals

Snakes have four ways to move. Since they do not have legs, they use their muscles and their scales to move.

The most known method is the serpentine mode, in which they move in an undulatory way by pushing themselves from any surface such as rocks, trees or earth.

The concertina mode is more used in enclosed spaces. The snake brakes the back of your body at the same time you push and extend the top. Then release the top and straighten and push the back.

The surrounding mode is used on slippery or loose surfaces. In this mode it seems that the snake releases its head forward while the rest of its body follows.

And rectilinear mode is a slow and straight way to crawl. The animal uses the large scales of its abdomen to attach itself to the surface while pushing forward.

Worms

Worms move on the surface using their bristles or hairs as anchors. That way, you can push forward or backward, using those muscles when contracting and stretching them.

Lizards

The 12 Most Commonly Drawn Animals 2

Lizards are not able to lift their body towards their limbs, so they have to crawl using their limbs and their tail.

Additionally, most species have small structures on their feet that allow them to stick to surfaces through frictional forces. These structures can carry up to 20 times the weight of the animal.

Caterpillars

The 12 Most Commonly Drawn Animals 3

Since the caterpillars do not have any bones in their body, they use their abdomen to move. The first step is taken by your belly, with the rest of the body following in an undulating movement. Caterpillars can travel on surfaces such as terrain and plants.

Leeches

The 12 Most Common Dragging Animals 4

Leeches have suction cups on the top and back of your body. This allows them to be dragged using a movement of two anchors: they anchor the lower part of their body and then push forward with the upper part.

Snails

The 12 Most Commonly Dragged Animals 5

Snails move using the muscles underneath the body. They contract and stretch the muscles that push them forward.

At the same time, snails release a sticky substance that helps to protect their walk; This causes less friction on the surface and the substance acts as a protective layer between the snail and the soil.

Crocodiles

The 12 Most Commonly Drawn Animals 6

Usually, crocodiles crawl using their belly. This walk is usually slow, although it can be faster depending on the situation in which the animal is.

At slow speeds, classic drag by the abdomen can be observed when your chest, stomach and tail fall flat on the surface. Its walk is similar to the rest of the lizards and reptiles.

Spiders

The 12 Most Commonly Drawn Animals 7

Spiders can basically crawl on any surface: glass, walls, ceilings, etc.

They have thousands of tiny hairs that create different points of contact between the spider and the surface, increasing the animal's ability to support itself.

Grass Lizards

They are a species of lizard without limbs, originating in Africa. The only tips they have are small tips.

They move in a manner similar to snakes, pushing forward by pushing against points of contact of the environment like rocks, plants or irregularities in the ground.

Bees

The 12 Most Commonly Drawn Animals 8

The bees have no skeleton, they have an exoskeleton that gives them structure, protection and support.

When bees crawl inside the flowers drinking the nectar, they use their legs to store pollen. This is essential when the plants reproduce.

Worms

Earthworms move using retrograde waves, alternating between swelling and contracting along their bodies.

The swollen parts of the body are held in place using setae or quetas, which are fine hair that will allow it.

Stencils

They are a family of lizards, including species of escincos, esquincos and eslizones. There are over 1,500 species of this genus and are quite diverse.

Most species do not have a pronounced neck; His legs are short although many species lack limbs.

In many species, its movement is incredibly similar to that of snakes, even more so than lizards with well-developed limbs.
