Found molted shell on the edge of the Great Marsh. Second photo was taken in an estuary in Florida, but shows a female with two males attached right before she is about to lay.
The horse shoe crab come up on land to lay their eggs, which are valuable to migrating birds. They are usually found in estuaries. They have hemocyanin in their blood, has copper which makes their blood blue. Instead of white blood cells like vertebrates the horseshoe crab have amebocytes. These amebocytes release a chemical when they come in contact with a pathogen and it causes the local blood to clot. This adaptation has helped them isolate dangerous pathogens and what has lead to their species survival. They are also commercially valuable for that blood used in the pharmaceutical industry, a quart could be sold for $15,000. Horseshoe shaped body, brown in color, and have telson (tail).
