Which outcome results when certain cephalopod species cultivate a bacterial microbiome exceeding a quorum sensing threshold?

💡 Explanation

Enhanced luminescence for predator evasion occurs because bioluminescent bacteria colonize light organs; crossing the quorum sensing threshold activates luciferase via gene regulation. Therefore, brighter light deters predators, rather than melanin synthesis or chemoreception increases.
