The show - The most numerous animals

The slide is the common name for arthropods in the Dual Leg class (Diplopoda). Called Double Legs because the rolling species have two pairs of legs in each combustion, except the first one is behind the head without legs. This phenomenon is caused because each of the "passages" of the slide are due to the two re-enter that.

The slide is the world's most ardent animal

The slide is a terrestrial vertebrate, it has a tubular or flat shape, divided into two parts: head and body. The head has a pair of short tentacles, the body has a lot of burning, sometimes several hundred burns. Except for head and foot burns and 2 to 4 burns each with 1 foot, each burn has 2 legs, so it has lots of legs. In the canyon of Panama, North America has a large rolling variety, with 175 bodies in total, 690 feet in total, it can be said to be the most abundant animal in the world.

When anyone touches, the roll is rolled up.

The slide does not have to have many legs like that. When it was just born, it had only 7 burns, the first time it was changed to 11 burning with 7 legs. 2nd molting increased to 15 burning, with 15 legs. After molting many times, the number of burning increases, the number of feet also increases.

Of course, there are many rolling varieties, with only 2mm long of its legs playing less than a Panama projection .

When rolling, the sides of the legs are active, the front legs of the hind legs turn into a wave, very rhythmic. Only things, many feet like that, but the speed is very slow, but in return they are very good burrowsmen. With their legs and body length moving in a wavy fashion, they easily opened the way to the ground. They also seem to have some technical ability to reinforce the tunnel by rearranging the soil around the tunnel.

Multi-legged species breathe through two pairs of breathing holes on each double burner. Each vents with an inner pocket, and connected to a trachea system. The heart runs along the length of the body, with an aorta pulling to the head. The excretory organ is two pairs of malpighian tubes , located in the middle of the intestine.

The mat is live in a damp place, in a leafy branch or in a pile of gravel. He ate fallen leaves, decayed substances, some ate young leaves and sweet sprouts, harmful.

The burner is not toxic, but it also has a defense. When anyone touches it, then curl up, lie still and not move, or follow another step, until it is out of danger, slowly crawl again. On the burners it has a bad gland, which is hard to smell, making it impossible for any animal to touch.
