This Science Screen Report examines different ways marine species confront their environments using elaborate, specialized survival adaptations. Parallels between hunting techniques and defensive methods are described by contrasting aquatic predators with more vulnerable creatures, which rely on camouflage and sophisticated mobility. The program emphasizes that the oceans are not only the cradle of life—they are also one-third of the planet’s surface, and in a very real sense an unexplored frontier. A viewable/printable instructor’s guide is available online. Correlates to National Science Education Standards. Produced in association with the Accreditation Board for Engineering and Technology and the Junior Engineering Technical Society. (23 minutes)
