Waiting for them are teams of lab workers, who capture the horseshoe crabs by the hundreds of thousands, take them to labs, harvest their cerulean blood, then return them to the sea. Why? Elizabeth Cox illuminates the incredible properties of horseshoe crab blood. Lesson by Elizabeth Cox, directed by Anton Bogaty. Thank you so much to our patrons for your support!
