Can cockroaches feel pain?
Whether cockroaches sense pain is unclear, although their neural system can respond to stimuli. It’s more likely that their responses to dangerous things are reflexes than conscious feelings of pain. While they may react to injury, scientists say their experience is not pain.
How big were cockroaches 300 million years ago?
