    Woah. Are horseshoe crabs like other crustaceans in that they eat pretty much anything including/mostly detritus?

    If thats the case, than how would it be beneficial to have blood that coagulates so easily?

    Wouldn’t every meal lead to a crab version of a stroke?

      Horseshoe crabs are not crusteceans, they are early chelicerates.

      They have an open circulatory system, where the blood (heamolymph) freely spills out of the arteries into surrounding tissues, so a small clot probably wouldn’t cause issues. Think of it like a cyst, sometimes if an infection can’t be removed by the immune system, your body will just enclose it in a capsule, so it can’t spread.
