Why are fish fish-shaped? - Lauren Sallan
2 days ago En
Check out our Patreon page: https://www.patreon.com/teded View full lesson: https://ed.ted.com/lessons/the-incredible-evolution-of-fish-bodies-lauren-sallan In tropical seas, flying fish leap out of the water, gliding for up to 200 meters, before dipping back into the sea. In the Indo-Pacific, a hunting sailfish swims up to 110 kilometers per hour. These feats are made possible by a fish’s form -- which in most species is a smooth, long body, fins, and a tail. Lauren Sallan explains why these features are so common, and what it reveals about fish. Lesson by Lauren Sallan, animation by Aeon Production. Thank you so much to our patrons for your support!
