Habitat
Spiders live basically everywhere but on the artic ice cap. They tend to thrive where there are a lot of insects. They can range in many sizes and colors which help them adapt to their environments. Some live in the deserts well others live on the mountains tops. Some come where we see them most during the winter are homes.
Scorpions live world wide. Although they do live almost every where they prefer it to be warm. They mostly come out at night to do there hunting. So people never see them.

Unique Facts
Some of the unique things about spiders are that they come in so many different colors. They help them blend into their enviornment. The largest spider is the Goliath tarantula from South America. The smallest spider is the male Patutigue. In the spider family, the males are normally smaller than the females!

Nervous System and Sensory Organs
Spiders and scorpions have nerves that run from their brain to all of the different parts of their body, just like humans do.

The Respritory System
Spiders and scorpions have what is called book lungs. They are very thin tissue that is folded. The oxygen is carried throughout the blood.

Reproduction and the Life Cycle
Scorpions and spiders reproduce in different ways. The major difference is that spiders lay eggs. Scorpions give birth to live young.
Scorpions do an interesting dance some call the "courting dance" to mate. The male will release a packet of sperm called a spermatophore and drag the female over it. Different scorpions will be pregnant for different amounts of time. Some will give birth after several months. Others won't give birth for over a year! They will have between 25 and 35 babies. The babies will stay on their mother's back until they molt for the first time. After that, they start to do things on their own. After they molt five or six times, they are an adult. Most scorpions live for three to five years, but some can live up to 25 years!
Male spiders and female spiders are always separate. Before they mate, they go through a long courtship. This helps the female to recognize the male as a potential mate instead of a tasty meal. Spiders also have spermatophores. Once the female has the sperm inside of her, she can lay her eggs. Once the baby spiders hatch, they can soon take care of themselves. They become an adult once they shed their skeleton.

Circulatory System
Spiders and scorpions both have what is called an "open circulatory system". This means that they don't have veins and arteries like we do. Instead, their blood exists all over their body. They have a tube shaped heart. The blood is moved around the body whenever the spider or scorpion moves. Their blood is not red like ours. It is colorless. Sometimes their blood is even poisonous!

Importance to the Environment
Spiders and scorpions are both very important to the food web. Without the scorpion, the desert would weaken. Spiders are very helpful to our environment. They eat pesky insects. This lessens the need for dangerous pesticides that can damage some plants or make people sick. Our world would be very different without these two animals.

Spiders and Scorpions
Excretory System
Spiders convert nitrogen waste into uric acid and excrete it as dry material. Scorpions eliminate waste threw the malpighian tubules expelled through anus as dry feces.

The Digestive System
The digestive system consists of a tube that goes from the mouth to the hind end. In the head and middle area the tube stretches out to form a stomach with strong muscles. When the muscles get tighter, they produce a powerful sucking action that pulls food into the stomach.

The Skeleton
There is a pair of legs for each section of the body. There is a thorax, abdomen and the head. Then the thorax, it is the area behind the head that separates the head from the abdomen. The largest part of the body is the abdomen, which contains most of the organs on the inside of the body.

The Exoskeleton
The exoskeleton is thick and tough, it is made of a chitin. It is also very bendable and works very well to help against predators or accidental injuries. There is a minus side to having an exoskeleton. It limits the size of the animal with it. The reason for this is because the muscle needed to lift the skeleton goes over the inside volume of the skeleton.
