This precise line drawing reveals the ventral morphology of the American horseshoe crab, emphasizing its six pairs of appendages-chelicerae, pedipalps, and four pairs of walking legs-each with specialized functions. The image also details the five pairs of book gills used for respiration and locomotion, and the prominent, spine-tipped telson that aids in righting the animal. The symmetry and segmentation reflect its classification as a chelicerate arthropod.
