Why do squids and isopods get bigger the deeper you go in the ocean? Isn't that incredibly counter-intuitive?
I mean, it's a common truth there's less plentiful food in the deep. Less plentiful food means more need for conservation of energy. Of course, that means creatures should be SMALLER and move LESS, yes?

Can someone please explain?

To fight the higher pressure they need less surface area per unit volume.

Then how do they eat enough to maintain that size?

Since N is higher at greater depths, and N is food for phytoplankton, and phytoplankton are the basis for the entire oceanic food web; I would say that it's not the truth that food is less available at greater depts

All those sinking dead animals probably provide plenty of food.
