Where are a spider's legs found?

A spider’s legs are found on the cephalothorax, which is the fused head and thorax region of arachnids. This anatomical structure serves as a pivotal area for various important functions, including locomotion, as it supports all eight legs. The cephalothorax also houses the spider's major sensory organs and mouthparts, emphasizing its role as a critical segment for survival and interaction with the environment.

Understanding this placement is essential for distinguishing spiders from other arachnids. The cephalothorax, as opposed to the abdomen, contains the legs, which makes it clear that the legs are not located in the abdomen, thorax, or head. This knowledge helps in identifying and understanding spider anatomy, which is foundational in fields such as entomology and pest control.
