Thanks to http://www.audible.com/minuteearth for sponsoring this video. A new fish counting method has revealed there are ten times more fish in the sea than we previously thought.* *But unfortunately, this doesn't mean we're not overfishing.

We try to leave jargon out of our videos, but if you want to learn more about this topic, here are some handy keywords to get your googling started: - Milky Way: Earth's home galaxy - The Malaspina Expedition 2010: A research project to explore ocean biodiversity by recreating the path of a late 18th Century scientific expedition. - Sonar: A technique that uses soundwaves to map out underwater objects. - Avoidance of Trawl: A behavior in which fish move out of the way of an incoming net, perhaps through bioluminescent signalling. - Bioluminescence: Light produced by a living organism. - Deep water fish: Fish who live more than 500m below the ocean surface in the Mesopelagic, Epipelagic, and Bathypelagic zones. Species featured in this video: - Stoplight loosejaws (Malacosteus niger) - Common Fangtooth (Anoplogaster cornuta) - Lanternfishes or myctophids (Family Myctophidae) - Bristlemouths (Genus Cyclothone): The most populous vertebrate on Earth. ___________________________________________ A big thank-you to our supporters on https://www.patreon.com/MinuteEarth : - Today I Found Out - Maarten Bremer - Jeff Straathof - Mark Roth - Tony Fadell - Muhammad Shifaz - 靛蓝字幕组 - Jagdtiger - Alberto Bortoni - Valentin - Antoine Coeur ___________________________________________ Credits (and Twitter handles): Script Writer: David Goldenberg (@dgoldenberg) Script Editor: Emily Elert (@eelert) Video Illustrator: Ever Salazar (@eversalazar) Video Director: Emily Elert (@eelert) Video Narrator: Emily Elert (@eelert) With Contributions From: Henry Reich, Alex Reich, Kate Yoshida, Omkar Bhagat, Peter Reich, Rachel Becker Music by: Nathaniel Schroeder: http://www.soundcloud.com/drschroeder _________________________________________ Like our videos?
