Why Fish Can’t Survive Below This Depth.

In 2022, a camera filmed a fish at 8,336 meters below the surface, the deepest fish ever seen alive. But below a certain depth, no fish has ever been found. In this video from Deep Atlas, we dive from the surface to the bottom of the Mariana Trench to find where that line is, and why it might exist. ⏱ Chapters 0:00 The deepest fish ever filmed 0:23 Meet the snailfish at 8,336 m 1:19 Where sunlight fades 2:18 The anglerfish and its lure 3:11 Bacteria, glowing lures and tiny males 4:10 What pressure does to the body 5:07 Into the hadal zone (6,000 m and below) 6:07 The record fish 6:51 Why fish stop: the TMAO theory 7:47 The limit near 8,200 m 8:41 Who lives below the line 9:37 Next dive ℹ️ Note: The visuals are original animations and illustrations, not real footage.

Fish may yet be found a little deeper. 🔔 Subscribe to Deep Atlas so you don’t miss the next dive #deepsea #ocean #marinebiology #mariana #documentary
