section outlines:

Arachnids and many other creepy crawlers need darkness and high humidity to live comfortably. For some, these factors are so essential for them to live. The forest floor is definitely the home of these creatures in the rainforest. Many people have misconceptions that arachnids and creepy crawlers are either black or brown and dull to look at. Well, that is so untrue. These creatures like many other species of fauna in the rainforest comes in many different colours and some striking as well. One such example is the Cobalt Blue tarantula. It has an amazingly beautiful metallic blue colour. Carry on down the page to find out more about these creatures and their interesting lives.

Centipedes are very long arachnids and body made up of segments. Each segment has a pair of walking legs, and together, it adds up to a lot of legs, like many other arachnids. In the front of the body is the head segment where two pairs of jaws. One pair is called the accessory jaw where it is used to handle food and old it to the mouth. The other pair that is the chewing jaws, as the name implies, is used to chew its food. Also, at the first segment, there are poison claws used in paralyzing its victim. They can grow up to a foot long.

At the other end of the centipede is its genital segment where the sexual organs are situated. Fertilizing occur with the female taking up a mass of sperm left by the male on a small web. The eggs are usually left in the soil. Centipedes cannot tolerate drying, because they lack devices for closing their respiratory openings found on their bodies. Thus the forest floor is a suitable habitat for these creatures where humidity level is high.

Centipedes cannot tolerate drying, since they lack effective devices for closing the respiratory openings. They minimize water loss by coming out only at night and hide at daytime.

Millipedes resemble centipede in some ways. Both of them have segmented bodies and many legs. But millipede definitely has many more legs and segments than centipedes do. Millipedes are also much gentler than centipedes, eating rotting woods rather than insects. With this, they are usually found on rotting logs. Some species of millipede even build impressive nest using excrements which hardens upon exposure to air. Millipedes too, are sensitive to desiccation. Species like the pill millipede often roll themselves up to form a pill like structure when threatened. They come in various colors usually reddish brown with shades of black and orange.
