The Cephalothorax (The Head) |
|||
|
This big long word stands for the head and thorax. On every spider, all 8 legs are attached to the cephalothorax. also connected to this are the jaws, eyes, abdomen, and the pedipalps. Pedipalps are like feelers. They are used for touch and taste. They are often mistaken for a pair of legs. the cephalothorax is main part of the body, considering everything is connected to it. |

Legs |
|||
|
|
All spiders have Eight legs. There are no insects with eight legs, which is the most common way to tell between a spider and an insect. All legs are connected to the cephalothorax. On the ends of all the legs are claws. These are used to grip webs and climb on surfaces. these claws are what let spiders climb upside down, vertical, and on smooth surfaces. |  |

|
Eyes |
|||
|
|
A common misconception is that all spiders have 8 eyes. Some spiders have 6 eyes, some don't have eyes. The eyes are arranged in two rows. Most spiders have poor vision, except the Jumping Spiders, which need good vision to see what they are jumping on. | ||
|
Fangs |
|||
|
|
The fangs aren't really a separate part of the spider's body. They are attached to the jaws of the spider. Some fangs point downwards to pin the prey down on the ground. Some point to each other so it grabs the prey and it can't escape the grip. The fangs are hollow so venom can flow to the tip of the fang where it goes into the prey. |  |

|
Breathing Pores |
|||
|
|
A spider has pores on the underside of the cephalothorax that allow it to breath. they are connected to small lungs. Some spiders also have air tubes called tracheae. | ||
