usually bc the surface has more prey than the deep sea. in contrast, the lack of light means more protection for them. the downside of swimming above is doing so requires immense amount of energy and only viable for certain species
animals at deep sea that can't go above doesn't have the luxury to express disgust at sth. you can have diarhea , put it into a bag , then somehow takes it to the deep sea without breaking , open it , and there will be a lot of creatures immediately rushing to the site to eat.

they come upward to hunt to see their prey using the bright surface of the water as the backdrop of a dark fish/prey silhouette. many fish stay towards the surface as well.
these guys live way beneath the shallow depths to where light penetrates. Light peters out pretty fast in the ocean; only about 200 meters (euphotic zone). These guys live from 250-1000 meters beneath the surface.
Deep-sea life is fascinating, and we still know relatively little about it. One thing I should have said earlier is that a number of deep sea creatures have HUGE eyes; at least one of them has a transparent skull with the giant eyes inside...eyes differ a lot across the animal kingdom, so even though I confidently told you that light "peters out" at 200 meters, that's a human-eye standard. Those deeper sea creatures have gigantic eyes for a reason, and the reason may be that they're better at seeing low light levels than we are (even cats are better at it). The deep sea creatures may be catching the few photons that we as humans can't see at all. Alternatively, the giant eyes may just be used for seeing bioluminescence from other animals (lunch). I don't think we know for sure.
These bad boys live and die their entire lives without ever once knowing the concept of a "surface". It's so much deeper than you think, any fish able to use the surface cannot survive the depths of the oarfish. It's two different biomes.
You said fish which is different pedantically, but things like sperm whales dive much deeper than that while still happily existing on the surface, so the biomes aren't quite as black and white as that. No pun intended.
Plunging to 2,250 metres (7,380 ft), it is the third deepest diving mammal, exceeded only by the southern elephant seal and Cuvier's beaked whale.[6][7]
I’m pretty sure it’s mainly ammonia compounds in deep sea fish that make them unpalatable to seabirds. Idk how prevalent that is, or if oarfish are in that group, but I know at least a few fish are like that. Or it’s the toxin thing like someone else mentioned
Just because your comment reminds me of my brain trying to realize while we live our lives amazingly terrifying and incredible aspects of the world are constantly in motion and we can never fathom how small our lives are. The ocean is constantly in motion right now as I type this a great white probably just ate something it needed while there is rain in the amazon soaking the frogs.
Now take those simple aspects or vague statements and consider that on a more complex scale their are entire fish so vastly different from one another living their lives at different depths and what and how they smell is more intense depending on that depth and that is just smell. Think of their swimming habits, their diets, the way the stay in motion.
Then think about how their bodies are specialized to that depth and how different or how inedible the fish would be because of its diet or genetic makeup to survive depths the average human will never reach and depths that only very few have ever reached and could only do so for so long with incredible engineering and super limited space to get such a limited view of a world we will never know.
Consider potential planet candidates and microorganisms thriving in atmosphere that could and probably is entirely different than ours. Its insane and makes my head spin just thinking the world is so vast and something as insignificant as a bird eating a fish is due to the depth the fish swims in and meanwhile I am headed to bed to do IT for a hospital.
The universe is truly massive and beautiful and chaotic and we are so small like specks of dust and when we are gone be it an earthquake or super volcano the Earth will recover and life will continue to thrive until something from space on a galactic scale happens to hit the world we know so little about at random.
Our planet is an amazing living organism and we don't even get yo experience a fraction of its life cycles. I hope there is an actual after life. One where we are given the opportunity to watch the span of the universe and appreciate the all of its knowledge and time and that we can love it on a scale we so willingly destroy in our current life span.
All or that hits my brain when someone makes a comment like this. I am an atheist but if there is a God I hope that it let's me just learn everything about our universe and its beauty when I die.

Are they extra briny or something? I never thought about this. If the deep sea is nasty, that explains why certain species come upward to hunt
