How many major body segments do spiders have?

1. Two

2. Three

3. Four

4. Five

The correct answer is: Two

Spiders have two major body segments, which are the cephalothorax and the abdomen. The cephalothorax, also known as the prosoma, combines the head and thorax and contains important structures such as the eyes, mouthparts, and legs. The abdomen, or opisthosoma, houses the digestive and reproductive organs, and sometimes the spinnerets used for silk production. Understanding the anatomy of spiders is crucial for pest control technicians, as it helps identify these creatures more accurately and understand their behaviors and interactions within their ecosystems. This knowledge can assist in the implementation of appropriate control measures when dealing with spider infestations.
