Who win in a fight a octopus or a spider?

In a fight between an octopus and a spider, the octopus would likely have the advantage due to its physical size, strength, and ability to deliver powerful strikes with its tentacles. Octopuses are also known for their intelligence and problem-solving abilities, which could give them an edge in a confrontation. However, the outcome would ultimately depend on the specific species of octopus and spider involved, as well as the environment in which the fight takes place.
