In the context of evolutionary arthopodial transformations, centipede ultimate legs exhibit a plethora morphological modifications and behavioral adaptations. Many species possess significantly elongated, thickened, or pincer-like legs. They are frequently sexually dimorphic, indicating role in courtship mating. addition, glandular pores occur more commonly on than walking legs, secretion, chemical communication, predator avoidance. this framework, study characterizes evolutionarily transformed Lithobius forficatus comparison with regular A comparative analysis using macro-photography, SEM, μCT, autofluorescence, backfilling, 3D-reconstruction illustrates that largely resemble but also feature series distinctions. Substantial differences found regard to aspects configuration specific podomeres, musculature, abundance epidermal glands, typology distribution sensilla, architecture associated nervous system structures. consideration characteristics, L. primarily serve defensive, sensory function.
