Yes, spiders do have brains. However, the brain of a spider is much different from the brain of a mammal like a human.
The nervous system of a spider is centralized in its cephalothorax, the front part of the body that’s a fusion of the head and thorax. In a sense, spiders have a kind of “fused” brain that occupies much of the cephalothorax. The spider’s brain is responsible for processing sensory information, controlling movement, and managing other functions necessary for survival.
While spiders do have brains, they are relatively small and simple compared to the brains of mammals. The complexity of a spider’s brain depends on the species, with more complex behaviors associated with more complex brain structures.
