Audience: Students; Grades: 9-12; Science.Scientists demonstrate how the struggle for survival drives evolution, introducing molluscs as animals that know the secrets of this competition to survive. Using the example of the abalone, introduces typical mollusk construction: the radula, shell, mantle and body design. Also films how abalones escape their predators by outrunning them, while cockles and moon snails use their foot to dig or remain firmly shut against their enemies. Biologist, Peter Ward, captures a chambered nautilus to demonstrate how evolution transformed a bottom feeder into a battleship-like warrior with spicules that increased its buoyancy. Also reveals how evolutionary features of the nervous system and body design of the squid propells it through the ocean and how the octopus developed a unique body design, camoflauge, and a large brain.
