What Is a Zombie Starfish
A zombie starfish is a sea star that continues to move or appear alive after losing most of its body, often due to injury, disease, or predation. The term highlights how these animals can survive with limited tissue and even regrow missing parts.
How Arm Loss and Regeneration Work
Sea stars can shed arms to escape predators, a process called autotomy. In some species, a severed arm with part of the central disc can regenerate into a whole new individual. This ability helps populations recover after damage.
Why Survival and Research Matter
Zombie-like sea stars are studied to understand tissue repair, immune responses, and the impact of environmental stress. Researchers use findings to monitor coastal ecosystems and track changes linked to warming waters and disease outbreaks Learn more about sea star biology.
