Read the passage given below carefully:

To most of us, the most fascinating thing about spiders is the webs they spin. But actually a spider the most amazing creature in many other respects. First of all, spiders are not insects. They belong to a group known as ‘arachnids’ and differ from insects in that they have eight legs, usually eight eyes, and only two parts to their bodies.

They can live on any type of climate and are found in every part of the world. They can live on the water, on the ground, depending on their species. They vary in size from 8 centimetres to that are so small that they are barely visible. Some spiders can go a whole year without water. One of spider, the large tarantula, eats birds and can live for as long as 15 years. Yet most spiders live just one year.

The silk in a spider’s web is manufactured in certain abdominal glands. The silk is forced through m tiny holes from the spinning organs at the tip of the abdomen. It comes out as a liquid which becomes solid on contact with the air.

There are many kinds of silk that a spider can spin. The sticky silk which the spider uses in its web catch its prey is the sticky one. The strong supporting spokes which are non-sticky and the silks in a cocoon in which the eggs are laid are actually soft and fluffy. Other silks that it weaves are hard even fibrous.

Even the shapes of spiders’ webs differ. Some make webs that are shaped like wheels and are commonly used for catching its prey. It is made by first forming a rectangle with heavy outer lines which form the foundation lines of the web. The spokes of the wheel are constructed next. Then comes a scaffolding of three to four spiels. The close, sticky silk spiral is built last.

Other webs that a spider spins are ‘sheet webs’. They are flat and are funnel-shaped. Sometimes, they are even dome-shaped masses of silk. The spider uses one side of the web to live in it. ‘Trap’ door spiders make a burrow with a lid at the top. It is disguised by sticks and dirt. A ‘Wolf’ spider builds a tunnel into the ground and lines the area with silk.

The European water spider builds a home in the shape of a bell. This is done entirely underwater! The spider then fills it with air brought from the surface in the hairs of its abdomen. Then she lays eggs and rears the young in this enclosure until they are old enough to build webs for themselves. Yet not all spiders build nests for themselves. Some of them just make a ‘home’ in a leaf, or a slice of tree bark instead.
