Final answer:
The subclass Coleoidea of class Cephalopoda, which includes squids and octopuses, possesses highly developed eyes for vision, and skin that can change color for communication and camouflage.
Step-by-step explanation:
The sense organs associated with the subclass Coleoidea of class Cephalopoda within Phylum Mollusca are primarily the eyes. Coleoidea, which includes creatures such as squids, octopuses, and cuttlefish, have highly developed nervous systems and complex, image-forming eyes that are considered among the most advanced in the animal kingdom. These cephalopods use their sophisticated eyes for hunting and navigation in the marine environment.
Moreover, cephalopods exhibit remarkable abilities for communication and camouflage through their skin, which can quickly change color and texture, thanks to specialized cells known as chromatophores. They also possess a keen sense of touch and a highly developed brain, making them very intelligent marine predators.
