what are some adaptation of horseshoe crab?

Horseshoe crabs have several adaptations that help them survive in their marine environments. Their hard, exoskeletal shell provides protection from predators, while their ability to burrow into sand allows them to evade threats and regulate their body temperature. Additionally, their unique blue blood contains a substance called Limulus Amebocyte Lysate, which is crucial for detecting bacterial contamination, making them vital in medical applications. Their compound eyes, which can detect light and movement, enhance their ability to navigate and respond to their surroundings.
