Centipedes are common predatory invertebrates whose capacity for suffering is poorly understood, yet they present interesting case studies in applying precautionary welfare principles.
The welfare significance of centipede interactions with humans remains deeply uncertain. Their nervous systems are relatively simple, but nociception and avoidance behaviour are documented. The precautionary approach to invertebrate welfare suggests minimising unnecessary harm while acknowledging limited evidence for significant suffering. More concretely, centipedes as garden predators benefit the entire garden ecosystem that supports welfare-relevant vertebrates. Pesticide use killing centipede populations has cascading effects through pest prey populations and up to insectivorous vertebrates. Exotic centipede keeping requires species-appropriate enclosures with humidity, thermal gradients, and appropriate prey.
