Horseshoe Crab Anatomy and Biology | Marine Life Guide #3047899 (License: Personal Use)

This high-detail illustration highlights the anatomical features of the Atlantic horseshoe crab, including its chitinous exoskeleton, compound eyes, and spiny lateral margins. The telson (tail spine) is prominently displayed, used for righting itself when overturned, while the book gills and walking legs are subtly suggested beneath the carapace. The image emphasizes its ancient lineage-unchanged for over 450 million years-and ecological importance in coastal ecosystems.

Used on marine biology educational pages, conservation websites, or aquarium resources to illustrate horseshoe crab morphology; targets users researching arthropod evolution, biomedical applications (e.g., LAL testing), or coastal habitat preservation.
