Nine-Armed Octopus Shows Remarkable Adaptability

Researchers in Spain observed an Octopus vulgaris, nicknamed Salvador, with nine arms due to unusual regeneration after a predator attack. Its bifurcated arm, resembling Dali's moustache, was initially used less for risky tasks, suggesting long-term memory of the injury. However, Salvador's nervous system adapted, integrating the ninth arm effectively into its environment exploration. This highlights the remarkable adaptability of octopuses.
