Adaptive radiation in arthropods represents one of the most remarkable examples of evolutionary diversification in the animal kingdom. Arthropods, belonging to the phylum Arthropoda, are characterized by their segmented body, jointed appendages, exoskeleton made of chitin, and highly developed sensory and locomotory organs. The phylum includes diverse groups such as insects, arachnids, crustaceans, and myriapods. Adaptive radiation in arthropods is primarily driven by their ability to exploit a wide range of ecological niches, structural modifications, and reproductive strategies, which have allowed them to colonize almost every habitat on Earth, from deep oceans to terrestrial and aerial environments. One of the most significant adaptations facilitating radiation in arthropods is the evolution of a segmented body with specialized appendages. Segmentation allows division of labor among body regions, leading to more efficient locomotion, feeding, and sensory functions. For example, in crustaceans, specialized appendages like maxillipeds aid in feeding, while chelipeds function in defense and predation. In insects, wings evolved from thoracic appendages, opening up the aerial niche and enabling flight, dispersal, and exploitation of new food sources. Jointed appendages allow precise movements and
