The Horseshoe Crab has been around 450 million years—before the dinosaurs! Interestingly, they have undergone little evolutionary change since then and are known as “living fossils". Addtionally, they have been hailed medical miracles due to amoebocytes in their blood, which is used to test whether vaccines are effective!
