Arthropod Arachnids

Do you know what an arachnid is? It's a spider... not exactly the most favored insect of all! Arachnids have some very distinct body parts that distinguish them.

1) Only two body parts the abdomen and the cephalothorax
2) they have 8 legs
3) simple eyes
4)feel by means of their setae or small hairs on their body
5)they use silk to build their homes, spin up their food, and make protective cases for their young
6) spiders hatch as mini replicas of their parents - no egg, pupa, adult

Spiders scare us because they have a special defense mechanism that uses poison. We fear spiders because some of them have very poisonous bites. Yet, when learning more about spiders we can see that not all of them are poisonous or deadly!
