Conquest of the Waters, The

• 1981 ----- color ----- 22 min ----- 16mm
• (Life on Earth series, Part 10) David Attenborough explores a variety of sea life beginning with the sea squirt, a simple structure which dates back to ancient time. Coral cliffs and dry seabeds are inspected for traces of early sea creatures. Scales, skulls and jaws have been discovered--the remains of the shark's ancestors. As fish spread to the lakes and rivers, they developed gills which enabled them to breathe in the warmer waters. Bladder bags also evolved which made the fish more buoyant in the shallow waters. Thus the origin of the modern bony fish, such as the trout.
