During the warmer months, especially at night during the full moon, horseshoe crabs emerge from the sea to spawn. 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. 為什麼? Elizabeth Cox illuminates the incredible properties of horseshoe crab blood.

Lesson by Elizabeth Cox, directed by Anton Bogaty.
