Horseshoe crabs are remarkable animals, beautiful in their weirdness. These "living fossils" evolved 450 million years ago and have lived through at least five mass extinctions fatal to the majority of multicellular lifeforms on Earth. Sea-dwelling relatives of spiders, horseshoe crabs can lay millions of eggs, have four pairs of eyes, and (importantly to us) have blue blood containing amoeba-like immune cells. These horseshoe crab immune cells are analogous to the white blood cells of in our bodies, which protect us against a wide range of pathogens.
