Cuttlefish Behavior and Physiology

Cuttlefish are adept at changing their skin color, surpassing chameleons in this ability. They use this skill to protect themselves, as they lack a hard shell. When threatened, they can adopt a defensive posture, changing color to stand out and appear larger, deterring threats. This behavior is not just for show; their muscle tissue contains potent toxins that can ward off rivals, ensuring their survival in the coral habitat.
