The limbs of the snakes have completely regressed in the course of evolution. Only a few species still have residual characteristics in the skeleton. In contrast to the sneaks (subordination of the lizards) they can also lick without opening their mouths. A special feature is their high number of vertebrae. On average there are 200, some species of snakes have more than 400.
|Ball python(Python regius), up to 1.5m |
The ball python belongs to the family of giant snakes and therefore does not have any poison glands. When hunting, it holds its prey with its teeth and wraps around it until it suffocates. Then the prey is choked down in one piece. The females of the pythons lay eggs and roll around them in order to incubate them. In contrast, boas give birth to live young.
|Green tree python (Chondropython viridis), up to 1.8 m |
The bright green tree python lives in the rainforests of New Guinea and Northern Australia. Its front teeth are greatly elongated, its tail has the function of a grasping organ. It is nocturnal and feeds on birds, frogs and rodents. Occasionally he comes to the ground to hunt. Unfortunately, it is always caught by humans and ends up on their dining table.
|Tiger python(Python molurus), up to 8m |
The tiger python is one of the largest snakes of all. Its weight is up to 100kg. He lives in Burma and, like boas, kills his prey by suffocating. In contrast to the boas, pythons have two rows of teeth in the upper palate. The preferred habitat of large pythons is the soil and water.
|Aesculapian snake(Elaphe longissima), up to 1.8m> Film / graphics |
With a length of up to 1.80 meters, the Aesculapian snake is one of the largest snakes in Central Europe. It lives on sunny heaps and in sparse forests. With the first warmth in spring it comes out of the stone cracks. She also loves to climb low bushes and shrubs. The adder likes to hunt mice, but its bite is not poisonous. Unfortunately, it is threatened with extinction.
|Smooth snake(Coronella austriaca), up to 0.9m |
The smooth snake can be recognized by its typical head markings. It has a horseshoe-shaped neck patch and a band that runs from the nostril over the eye to the throat. Smooth snakes occur in almost all of Europe. The snake defends itself violently when attacked, but its bite is non-toxic. It feeds on lizards, slow worms, smaller snakes and mammals.
|Pointed snake(Elaphe oxycephala), up to 2.3m |
The pointed head snake, which lives in Asia, is a non-poisonous climbing snake and, like all other snakes, has a long, two-part tongue. The tips of the tongue constantly supply fragrance molecules to the Jacobsonian sensory organ located in the oral cavity. The two-part tongue is of great importance for the snake when moving and hunting, because only then can it accurately assess the direction.
|Dice snake(Natrix tesselata), up to 1.5m |
The dice snake can be recognized by the typical "cube pattern" of dark, lengthways arranged spots. Cube snakes live in south-eastern Europe. There are also isolated occurrences in Ticino. In Germany only a few specimens still live on the Moselle, Nahe, Lahn or Elbe. Cube snakes love warmth and can be found near larger bodies of water. They do excellent diving. The snake is non-poisonous, its hunting behavior is similar to that of the grass snake.
|Green mamba(Dendroaspis viridis), up to 2.7m |
Mambas live in trees and are very much feared in West Africa, as their bite is very quick to kill. Fortunately, however, the animal is very shy and avoids humans. The poisonous snake is particularly agile in the branches of trees and hunts its prey such as birds and tree-living amphibians there. The victims are quickly killed by the poison.
|Uraeus snake (Naja haje), up to 2.4m |
The uraeus snake, one of the cobras, shows the typical threatening posture of the spread pronotum in the photo. The cobra can strike at lightning speed and is quite biting. According to the legend, Cleopatra is said to have killed herself with the poison of a uraeus snake. In fact, their venom is not as effective as that of the largest cobra, the 4-meter-long king cobra. The nocturnal uraeus snake hunts for small mammals, birds, other reptiles and toads.
|Aspic viper(Vipera Aspis), up to 0.85m |
The aspic viper can be found in southern Europe, in the Black Forest, in the Jura and in the Alps. It is similar to the adder. The males have a zigzag band on their backs, while the females are more inconspicuously colored. Aspisvipers live on sunny and steep slopes. The bite of the venomous snake is usually not life-threatening, but it can lead to swelling, paralysis and in rare cases to nausea, vomiting, palpitations and attacks of dizziness.
|Copper head(Agkistrodon contortrix), up to 1m |
The copper head can be recognized by the red-brown or cinnamon-colored cross bars. Copperheads often appear on the edges of forests in Arkansas. In the southeastern United States, most snake bites are caused by copper heads. Fortunately, only a few are fatal because they are not as venomous as those of the rattlesnakes.
|Diamond rattlesnake(Crotalus adamanteus), up to 2.5m |
The diamond rattlesnake is the largest of all rattlesnakes. It is found in the southeastern United States and is one of the most dangerous venomous snakes, as it injects a lot of venom with one bite. Adult animals eat rabbits themselves. Young animals attack smaller birds as soon as they hatch.
|Texas rattlesnake(Crotalus atrox), up to 2.2m |
The Texas rattlesnake, like the diamond rattlesnake, is much feared. If it feels threatened, it holds the body upright in an ascending spiral, only to strike at lightning speed. Most of the snake bite deaths in the United States are attributable to them.
|Uracoan rattlesnake(Crotalus vegrandis), up to 2.5m |
The Uracoan rattlesnake is found in Eastern Venezuela. The vertical pupil and the protruding eye shields give the rattlesnakes a "sinister look". They love dry, stony areas with lots of undergrowth, where they like to hide in rock niches. Their diet consists predominantly of mammals, with the mice making up the largest proportion. Rattlesnakes give birth to their young alive.
|In rattlesnakes, the tip of the tail has been converted into a warning system. The scales of the skin are thickened and form interlocking segments that clash when the tail shakes. With this, the snake warns large mammals that graze on meadows and share their habitat with them, so that they themselves are not trampled.|
|The rattlesnakes have an opening between the eye and the nostril in which the pit organ is housed. The pit is spanned by a thin membrane, behind which there is an air-filled chamber. Nerve cells are located in the membrane and can perceive the slightest temperature differences between the outside temperature and the temperature in the air chamber. The snake recognizes the slightest temperature difference of 0.01 ° C and can practically see at night. The presence of two pit organs allows the snake to locate the direction of the heat-radiating prey.|
|White-lipped pit viper(Trimeresurus albolabris), up to 70cm |
The bright green white-lipped pit viper lives in the bush forests in the Indian lowlands. It feeds on tree frogs, geckos, fledglings and mice. The venomous snake is not very aggressive. She gives birth to about 12 young and is often bred in terrariums and zoos.
