Horseshoe Crab Anatomy Diagram - Educational Illustration #3706602 (License: Personal Use)

This precise line drawing depicts the underside of a horseshoe crab (Limulus polyphemus), revealing key anatomical features including six pairs of appendages-chelicerae, pedipalps, and four pairs of walking legs-plus the distinctive book gills and the elongated, spine-like telson. The symmetrical arrangement emphasizes arthropod segmentation and functional morphology adapted for benthic life. Fine linework captures joint articulation and sensory structures critical for feeding and locomotion.

Used in educational materials such as textbooks, university entomology/marine biology courses, museum exhibits, and online learning platforms to teach arthropod anatomy and evolutionary biology; matches user intent for academic study, species identification, or comparative anatomy research.
