Can deep sea fish live in shallow water?
An important think to realize about deep sea fish is that they cannot survive in shallow water. So the way their bodies work is based on surviving high pressure so they will not survive low pressure. The main way these fish are adapted to high pressure is having different cell membranes.
Is salmon a deep sea fish?
Salmon are native to tributaries of the North Atlantic (genus Salmo) and Pacific Ocean (genus Oncorhynchus). Salmon are intensively farmed in many parts of the world. Typically, salmon are anadromous: they hatch in fresh water, migrate to the ocean, then return to fresh water to reproduce.

What happens if you take a deep sea fish to the surface?
Deep sea fish sometimes arrive at the surface with their inner organs popped out of their mouth. They have different lipid types than us, because lipids are packed together differently at high pressures, and lowering the pressure on their lipids can make them malfunction.
At what depth do most fish live?

Are deep sea fish safe to eat?
Scientists had for a while now known that fish that feed in deep waters, where those bacteria are found, are more toxic than shallow water fish: in 2009, Popp and colleagues from University of Hawaii, Manoa, reported that big fish culled from large depths have higher mercury concentrations than fish harvested in
