Cockroaches are known for their resilience, but one of their most astonishing feats is surviving without their head for weeks. This is possible because cockroaches don’t rely on their heads to breathe; they have small openings called spiracles located along their body segments that allow them to intake air. Without a mouth to drink water, they eventually die of dehydration. This unique ability underscores the adaptability and survival skills of cockroaches, contributing to their reputation as one of the most enduring species on Earth.
