      Horseshoe “blood” is blue, and it’s not actually blood it’s hemolymph. It is blue crab blood. Blue blood from a crab.

        Blue blood from a horseshoe crab yes. Blue crabs are also a thing and horseshoe crabs are always referred to with the word horseshoe in front. So calling them just crabs with the word blue in front is a poor choice if one cares about communication.

          They weren’t in this case, so that “always” seems to be a stretch.

          if one cares about communication.

          It’s made clear in the article. If one cares about communication they’re reading past a headline.
