Insects, arachnids, and crustaceans are closely related arthropods with distinct characteristics and ecological roles. Insects possess diverse body plans, adapted for flight and a wide range of habitats. Arachnids, known for their exoskeletons and venom, include spiders, scorpions, and ticks. Crustaceans, predominantly marine, encompass crabs, lobsters, and shrimp, playing crucial roles in ocean ecosystems. Camouflage and mimicry, strategies used by these arthropods, provide fascinating insights into their survival and reproductive success.
