The way of life of the sand lizard - biology

Do you already have one Sand lizard seen? Maybe you got lucky and saw her sunbathe - or maybe she ran away quickly. Today we want to take a closer look at the sand lizard.

Sand lizard - appearance and characteristics

The sand lizard can reach a total length of up to 25 cm. The length from head to torso (head to torso length) is only about 10 cm - the tail is therefore longer than the rest of the body.
The sand lizard is one of the Reptiles, which are also called reptiles. So your body is dry Horn scales covered. As the sand lizard grows, the scales don't grow with it. Therefore skins the sand lizard: it throws off the scale that has become too small when it has developed a new, larger one. The color of the shed dress depends on the sex and age of the sand lizard, as well as the time of year. Often it has a green basic color, with a brown pattern extending over the center of the back and tail.

The sand lizard is excellent see and smell. The sensory cells that are responsible for smelling are located on the roof of the mouth and not, as is the case with humans, in the nose. Therefore, the sand lizard needs its forked tongue to smell: through that Flickering it absorbs odorous substances from the environment. Then she presses her tongue against the roof of the mouth in order to perceive the odorous substances.

Sand Lizard - Locomotion

The sand lizard's legs sit to the side: this is why the belly is only just above the ground while walking. The sand lizard always uses opposing limbs to move: it moves the left front leg at the same time as the right hind leg and then the right front leg with the left hind leg. This is also known as Cloister or Diagonal gait. The spine always curves in opposite directions. Seen from above, it looks like the sand lizard is moving meandering move around.

Sand lizard - habitat

The sand lizard is a cold-blooded Animal. This means that their body temperature adapts to the environment. She therefore prefers dry and warm areas where she can sunbathe undisturbed - because then her body temperature and thus her activity is increased. But if it is in danger, it likes to withdraw into overgrown areas. For example, it lives on embankments or on roadsides. There she can sunbathe, but also take refuge in the thicket.
In winter the sand lizard retreats to a frost-proof hiding place. When it's very cold, her body temperature drops so much that she falls into a Rigid expires. The sand lizard then stops moving and its heartbeat and breathing slows down.
In spring, when the temperature rises, the activity of the sand lizard is increased again by warmth.

Sand lizard - food

The sand lizard feeds mainly on insects. For example, woodlice and flies are among their prey spectrum. In addition, it also feeds on spiders and earthworms.

Sand lizard - reproduction

Sand lizards are loner and find each other only to pairing with conspecifics together. The mating season is in May - then reproduction takes place. To do this, both females and males press theirs Sewers, the body exits of the genital organs. The eggs are fertilized in what is called the female body internal fertilization designated.
After a few weeks, the female will seek out Egg laying a sandy and sunny place. She digs a hole in which she lays up to 15 fertilized eggs. She buries the eggs and does not hatch them herself. The eggs get the heat they need to develop from the surrounding soil. They hatch after about eight weeks Young animals. They break through the eggshell with the help of the so-called Egg tooth. The young animals are fully developed and can look for food independently.

Sand lizard - enemies

To the Predators The sand lizard includes snakes, hedgehogs and birds. If they are hunted, however, they can often escape due to their rapid locomotion. They also have another trick up their sleeves: they can shed part of their tail, which twitches for a long time after shedding and thereby distracts the pursuer. During this time, the sand lizard can disappear into the thicket.
After shedding, the tail grows back. The original tail spine is replaced by a cartilage rod - the sand lizards cannot shed their tail a second time.
