**Molluscan Countermeasures for Shell-Less Living** In adapting to a life without a protective shell, mollusks have developed a range of countermeasures. Below is a checklist of potential adaptations that mollusks may employ. Please select all that apply: - □ Increased metamerization used for flexibility - □ Torsion - □ Open circulatory system - □ Increased motility used for fleeing - □ Lungs for greater oxygen supply - □ Development of parapodia - □ Use of camouflage - □ Increased mucus production These adaptations may enhance their survival and functionality in various environments.
