Blue-blooded: Horseshoe Crabs, copper-based circulatory system—
455 Million Years in the Making and in Peril

Horseshoe crabs are well-known as "living fossils," with an ancestry reaching back 455 million years to the doorstep of the Cambrian.  They provide food resources for millions of migratory birds each year.  For humans, they are a pharmaceutical necessity because their blue blood provides LAL, an extract that detects Gram-negative bacteria, helping to prevent infections from surgery or injected drugs in hospitals around the world.  They have been the subject animal for a Nobel Prize award.  And, they are just "cool," full of copper-based, blue blood.

Today they are the subject of several assaults. In spite of their longevity, these animals now face growing threats to their continued survival. This talk will cover the dire problems faced by these critical species.
