_____ are among the most radioresistive species.

Cockroaches are considered among the most radioresistant species due to their unique biological and physiological traits. Their survival mechanisms include effective DNA repair processes that allow them to withstand higher radiation doses than many other organisms, including humans. Research indicates that cockroaches can tolerate about 6 to 15 times more radiation than humans can endure without significant damage.

This resilience is linked to their simple body structure, rapid reproduction rate, and evolutionary adaptations that have equipped them to cope with extreme environmental conditions, including exposure to radiation. Their ability to repair cellular damage quickly and efficiently contributes to their reputation as a hard-to-kill species in harsh environments. Thus, their remarkable resistance to radiation solidifies cockroaches' position as one of the most radioresistive organisms.
