Meet a Fish that Should have Died with the Dinosaurs - but didn't; Featured on The Missing Link, a BBC2 documentary that aired in 2001. Seventy million years after the extinction of the dinosaurs, a bizarre blue fish is captured. The coelacanth, over 360 million years old, with spiny scales, rounded fins and an extended tail, is thought to be one of the original links between sea-dwelling and land-dwelling life. From underwater quests for hidden populations to the dissection of the coelacanth's unique organs, this gripping scientific drama brings to life the thrill of discovery.
