Horseshoe Crab reproduction and life cycle

It is a fascinating creature that has been around for over 450 million years. These unique animals are not actually crabs, but they are closely related to spiders and scorpions. These crabs live in the ocean and can be found on the coasts of North America and Asia. These creatures have a hard exoskeleton and can grow to be up to 20 inches long. They get their name from their horseshoe-shaped body. These crabs are scavengers and feed on clams, worms, and other small creatures that they find in the sand. These creatures mate in the spring tides, and the female lays her eggs on the beach. The male fertilizes the eggs and then buries them in the sand. The eggs hatch after about two weeks, and the young crabs spend the next few years in the safety of shallow water before moving out to deeper water when they are fully grown.

It is used to test for endotoxins, which can cause sepsis, a potentially fatal condition. In addition to its medical uses, their blood is also used as bait in fishing. The crabs are attracted to the bait, and then fishermen can catch them and use them for food or sell them for their shells. Consequently, these crabs play an essential role in both the culinary and fishing industries.
