NOVA "Ancient Creature of the Deep" explores changing views about the coelacanth, which was once considered the missing link between fish and four-legged creatures.

The most famous "living fossil" is the coelacanth (see-la-kanth), a huge primitive fish once thought to have died out before the dinosaurs. NOVA tells the amazing story of its rediscovery in 1938, how live specimens were captured on video and how new colonies of the ancient fish have recently been found, raising hopes for its continuing survival.
