Horseshoe Crab Ventral Anatomy Diagram - Educational Illustration #3047903 (License: Personal Use)

This precise anatomical line drawing reveals the underside of a horseshoe crab, including its six pairs of appendages-chelicerae, pedipalps, and four pairs of walking legs-along with the distinctive book gills and the elongated, spine-like telson used for righting itself. The symmetrical layout emphasizes evolutionary conservation and functional morphology critical to understanding arthropod phylogeny. The illustration is rendered in clean linework suitable for textbooks, museum displays, or digital learning modules.

Used in educational contexts such as biology textbooks, marine science websites, museum exhibits, and classroom handouts to teach arthropod anatomy and paleozoic survivor species; matches user intent for academic study, species identification, or curriculum development.
