Legless reptile: brown squirrel

At first glance it seems that it is impossible to confuse a worm and a reptile. But it turns out that among the reptiles there is an animal that is surprisingly similar to an earthworm.

This representative is called a brown reptile, the second name is ash blanus (from Latin Blanus cinereus).

This reptile has no legs. Brown dvukhodka is a representative of the amphisbene family. The reptile is small in size, the body of an adult reaches 10-20 cm in length.

They have a small head with a pointed shape and a tail ending with a blunt end. The body of the brown dvukhka has a cylindrical shape and is covered with hard skin, which is divided by longitudinal and transverse annular grooves into small rectangles and looks similar to scales.

Brown squirrel (Blanus cinereus).

An interesting fact: the ash lung has developed the left lung, while the snake relatives amphisbene only developed the right. There is no explanation for this fact. Another difference between a brown two-wheeler and snakes is eyes. Snakes have perfectly developed and distinctly noticeable eyes, as you know, the snake look is widely known, many are afraid of it.

Ashen blanus is a legless reptile.

And in these reptiles, the eyes are almost invisible, they are hidden under the skin and look like two small dark spots. This arrangement of the eyes protects them from ingestion of specks and particles of soil. It also allows them to recognize light and darkness, and also to see the contours and outlines of large objects, but no more. The imperfection of vision in the brown dvuga is compensated by the excellent development of the organs of smell, touch and taste. She can find food that is under a thick layer of earth.

Outwardly, blanus is more like an ordinary earthworm.

These reptiles live in underground tunnels. They appear on the surface either after rain, or if tunnels dug by them were damaged or destroyed during agricultural work. Preferred living conditions are humus and sandy soils, forests. It is noteworthy that ash blanus is the only representative of the entire family that lives in Europe. Reptiles can be found in Portugal, Spain and in the northwestern regions of Africa.

Their diet includes ants, worms, millipedes, and various invertebrates. Often, a brown dweller can be seen in the anthill, because there she will find a lot of food.

A curious fact: the brown two-wheeler can move in two opposite directions - both forward and backward. This is very convenient for reptiles, especially when they move along narrow underground passages and there is no opportunity to turn around. While moving throughout the body, reptiles run through clearly visible waves. They are caused by the rapid movements of the trunk rings, which either converge or diverge.

During movement, the body of the blanus begins to “worry.”

It may seem that the body of the brown dvukhta changes in size, then decreasing, then increasing again, by analogy with the earthworm. But this is not so. The skin of the ash blanus does not adhere to the body loosely, essentially being a movable leather bag that folds along the rings and thus provides reptiles with movement in any direction. When the blanus is on the surface, it can move in the same way as snakes, by bending the body in different directions.

To breed, the blanus lays eggs.

Brown dvuhhodka refers to the oviparous. Usually the clutch consists of 2-6 eggs. The eggs are round in shape and covered with a translucent thin shell. The eggs of the female blanus are laid in the nests of ants. The female protects the clutch until the cubs are born.
