Spiders are among the most feared and misunderstood animals, but emerging research suggests they may have more complex inner lives than previously assumed.
Recent research on jumping spiders suggests they enter sleep-like states with eye movement and limb twitching, raising questions about their potential for dream-like experience. While certainty about spider sentience remains elusive, the precautionary principle suggests minimizing unnecessary killing. Spiders provide enormous ecological services as predators of pest insects. Relocation rather than killing is a practical option in most household encounters.
