Monterey Bay Aquarium Research Institute

MBARI's YouTube channel The Monterey Bay Aquarium Research Institute films deep-sea animals with remotely operated vehicles, so you see creatures in their own habitat, often narrated by the scientists who study them. Expect jellies, siphonophores and squid that look invented, plus clear explanations of what the research actually found. Start with What the Vampire Squid Really Eats. In under five minutes, researchers Henk-Jan Hoving and Bruce Robison show how this animal gathers sinking marine snow with long filaments, a way of feeding unknown in any other cephalopod. Then try the episode on why thousands of octopuses gather at deep-sea thermal springs.
