Horseshoe Crab: Ancient Marine Arthropod with Unique Anatomy #3706594 (License: Personal Use)

This scientific illustration depicts a horseshoe crab, an ancient marine arthropod belonging to the class Merostomata and order Xiphosura. Key features include its broad, domed prosoma (carapace), six pairs of legs (some modified into chelicerae and pedipalps), and a long, rigid telson used for steering and righting itself. Despite its name, it is more closely related to spiders and scorpions than true crabs.
