Synopsis: RITUAL OF THE SPRING TIDE documents the ancient spawning migration of horseshoe crabs to the Delaware Bay. The spring arrival of these living fossils marks the appearance of millions of migratory shorebirds, many of which have flown non-stop from the southern-most reaches of South America. People also eagerly anticipate the crabs arrival in an attempt to unlock new life saving biomedical discoveries from the unique physiology of this primitive organism. Thus, a ritual that has persisted for eons sets the stage for this story about a remarkable ancient organism and its modern beneficiaries. Time: 17 min Level: High School-College |
