From the Ted Talk by Heidi M. Sosik: The discoveries awaiting us in the ocean's twilight zone
Unscramble the Blue Letters
Let me show you a recent example that has changed our thinking. siltelate tracking decvies on animals such as sharks are now showing us that many top predators regularly dive deep into the twilight zone to feed. And when we map their swniimmg patterns and compare them to satellite data, we find that their feeding hot stpos are linked to oaecn currents and other features. We used to think these animals found all of their food in surface waters. We now believe they dpened on the twilight zone. But we still need to figure out how they find the best aeras to feed, what they're eating there and how much their diets depend on twilight zone species.

Original Text
Let me show you a recent example that has changed our thinking. Satellite tracking devices on animals such as sharks are now showing us that many top predators regularly dive deep into the twilight zone to feed. And when we map their swimming patterns and compare them to satellite data, we find that their feeding hot spots are linked to ocean currents and other features. We used to think these animals found all of their food in surface waters. We now believe they depend on the twilight zone. But we still need to figure out how they find the best areas to feed, what they're eating there and how much their diets depend on twilight zone species.
