Despite their name, they are not crabs or even crustaceans; they are chelicerates, more closely related to arachnids like spiders, ticks, and scorpions. The body of a horseshoe crab is divided into three main parts: the cephalothorax, abdomen, and telson.</description><pubDate>Thu, 01 Oct 2026 21:37:00 GMT</pubDate></item><item><title>Horseshoe crab | Blood &amp; Facts | Britannica</title><link>https://www.britannica.com/animal/horseshoe-crab</link><description>Horseshoe crab, common name of four species of marine arthropods found on the east coasts of Asia and North America. They are not crabs, however, and are related to scorpions, spiders, and trilobites. Two species are harvested for their coagulogen, which is used to test for the presence of gram-negative bacteria.</description><pubDate>Fri, 02 Oct 2026 08:14:00 GMT</pubDate></item><item><title>Horseshoe Crab History | Sacred Heart University</title><link>https://www.sacredheart.edu/academics/colleges--schools/college-of-arts--sciences/departments--schools/biology/project-limulus/horseshoe-crab-history/</link><description>Horseshoe Crab History Limulus polyphemus has existed for over 300 million years.

Despite its ancient origins, the horseshoe crab has managed to persist through the ages. Because the horseshoe crabs we see today are mostly the same in shape and structure to those seen in the fossil record, horseshoe crabs are referred to as "living fossils."</description><pubDate>Wed, 30 Sep 2026 22:49:00 GMT</pubDate></item></channel></rss>
