How Starfish Protect Themselves — Passage

Starfish, or sea stars, have evolved a fascinating array of defense mechanisms to survive in their marine habitats. These echinoderms employ various strategies to deter predators and ensure their survival. Their tough, spiny exoskeleton serves as a primary defense, making them difficult for many predators to consume. Some species can change their color to blend with their surroundings, a form of camouflage that helps them avoid detection. Perhaps their most remarkable defense is autotomy - the ability to voluntarily detach an arm when grabbed by a predator, later regenerating the lost limb. Some starfish species produce noxious chemicals or mucus to repel potential threats. These diverse protection methods showcase the incredible adaptations of starfish and highlight their resilience in the face of oceanic challenges, making them excellent subjects for studying evolutionary adaptations in marine ecosystems.
