What is a Spider?
You've seen them in your house, and in your yard. They're spiders. But there is more to these little guys than just their cobwebs.
Spiders can be interesting if you take the time to get to know them.
Spiders have two parts to their bodies. The front part is where the head is, and the mouth. It is also where all the legs are attached. They back part doesn't have any legs!
The back part does have many other things, though. The back part of the body has the lungs. Many spiders have what are called book lungs. Their lungs open to the outside of their body! Their lungs are in lots of thin leaves. They look like the pages of an open book.
The air passes over the lungs. That's when the lungs suck the oxygen out of the air.
Some spiders breathe air through a hole. They call this a trachea hole. The air goes through a tube to the book lungs.
Some spiders just have book lungs. Some just have a trachea hole. Some have both.
Many spiders have eight legs, but some have more. Their legs all work together to move the spider forward. Some spiders can even move sideways or backwards. Other spiders can only go forward. They have to turn around to go a different way.
Most spiders' legs are much longer than their bodies. Some spiders have legs that are over ten times as long as their body is. In America, one of these spiders is called the daddy long legs.
