How do fish survive in deep sea and why do they die when you take them to water higher up?
In: Biology
Water pressure increases as depth increases. A fish that is born and lives it’s entire life deep has a body used to those environmental conditions. When a fisherman reels in a fish like this, it’s eyes and such puff out and can kill the fish if not returned back to the water quickly. If the fish can return back to depths in time no permanent damage will be done.
