The Limulus Horseshoe Crab is neither a horseshoe nor is it a crab. Genetic tests show that this interesting and impressive arthropod is actually closely related to arachnids and this impressive display accents its status as a "living fossil". Ethically harvested and mounted in this museum style shadow box for excellent preservation and display, this is a must have for any collection. Dimensions: 19" x 15" x 3"
