Detailed explanation-1: -The compound eyes of flying arthropods, such as dragonflies, enable them to analyze a fast-changing landscape during flight. Compound eyes can detect the movements of prey, mates, or predators, and also can detect colors.

Detailed explanation-2: -VISION IN ARTHROPODA Phylum Arthropoda has two types of eyes for the purpose of vision-simple eye and compound eye. Of these, the compound eye has evolved as a unique feature in this phylum and is not found elsewhere. The compound eye is fund most commonly in insects as well crustaceans.

Detailed explanation-3: -The phylum Arthropoda contains a wide diversity of animals with hard exoskeletons and jointed appendages. Many familiar species belong to the phylum Arthropoda-insects, spiders, scorpions, centipedes, and millipedes on land; crabs, crayfish, shrimp, lobsters, and barnacles in water (Fig. 3.72).

Detailed explanation-4: -The incredible diversity and success of the arthropods is because of their very adaptable body plan. The evolution of many types of appendages-antennae, claws, wings, and mouthparts-allowed arthropods to occupy nearly every niche and habitat on earth.

Detailed explanation-5: -They possess an exoskeleton. They have jointed appendages. Their body is segmented. They are bilaterally symmetrical. They possess an open circulatory system.
