Horseshoe Crab (Limulus polyphemus)

The Horseshoe Crab is mostly greenish brown to light tan in color. The dorsal part of the body is rounded, and it has a long spike for a tail. The Horseshoe Crab is really not a crab, but more closely related to spiders. Horseshoe Crabs can grow very large, up to 12 inches in diameter. When small, they are very efficient scavengers and are exceptional at aerating sand beds. The Horseshoe Crabs dig through sand in search of worms and any organic debris as a food source. It will move the substrate around almost nonstop. Although it may find some food scavenging, its diet should be supplemented with meaty items such as pieces of squid and shrimp.

This crab is guaranteed for live arrival.
