Crash: A Tale of Two Species

Season 26 Episode 7 | 53m 56s

Loading Player...

This is the story of the fabric of life, and how all species are connected. At its center is the horseshoe crab, a creature that has remained virtually unchanged for eons. Its annual spawning produces millions of eggs that are the lifeline for a tiny bird, the red knot. But horseshoe crab numbers are plummeting, and the pyramid depending on this age-old creature is about to come crashing down.
