These video clips introduce Earth science students to a variety of creatures that inhabit hydrothermal vents on the ocean floor. The introduction describes how scientists captured the images using submarines and remote cameras. The first video is a three-dimensional animation that shows the landscape of the ocean floor. Five live-action clips show sulfide particles erupting from the vents, tube worms retreating from the camera, and plant-like sulfide worms that appear to be fighting. Students also see close-up views of an octopus eye and the tiny pandorae worms that live on the larger tube worms. A descriptive caption accompanies each video. Movie controls allow students to repeat, pause, or step through the animation, which can give students more time to analyze the images. Copyright 2005 Eisenhower National Clearinghouse
