Jellyfish are not really fish. They are invertebrate animals. This means that unlike fish or people, they have no backbones. In fact, they have no bones at all.

Jellyfish have stomachs and mouths, but no heads. They have nervous systems for sensing the world around them, but no brains. They are made almost entirely of water, which is why you can look through them.

Some jellyfish can glow in darkness by making their own light. The light is made by a chemical reaction inside the jellyfish. Scientists believe jellyfish glow for several reasons. For example, they may glow to scare away predators or to attract animals they like to eat.

Most jellyfish live in salt water, apart from a few types that live in fresh water. Jellyfish are found in oceans and seas all over the world. They live in warm, tropical seas and in icy waters near the North and South poles.

Gold is a precious metal. Gold is used as ornaments or as money.

Gold is found in many places, but in a small supply. It is often found on the surface of the earth. Since gold is a heavy substance, it is sometimes found loose on bottom of rivers. The gold is found together with sand and rocks, and must be separated from them. It is simple to search for this type of gold.

It is not usually necessary to drill for gold, but when a layer of gold is located deep below the surface of the earth, it is possible to drill a hole into the ground. Engineers have developed modern process for removing gold from rocks.

Since gold is not very hard, it is sometimes melted and added to other substances for making rings, coins, and art objects. It will be priced forever because it is beautiful, rare, and useful.

The plane with largest wingspan ever built was nicknamed the Spruce Goose. The wingspan of the Spruce Goose was 320 feet (almost 100 meters), and the plane weighed 200 tons. It was so big that it needed eight engines to power it.

The plane was designed by Howard Hughes in response to a U.S government request for a plane that was able to carry a large cargo for the war effort. It was made of wood because wood is a less critical material in wartime than metal.

The plane was so difficult to build that it was never really used. It was flown one time only, by Hughes himself on November 2, 1947; during that flight, it traveled a distance of less that one mile over the Los Angeles Harbor, but it did fly. Today, the Spruce Goose is on exhibit for the public to see in Long Beach, California.

According to the text, why did the plane need eight engines to power?
