Ocean Pressure Question. HUGE!!! (detail is LONG)!?

Look,your knowledge is not full enough to explain it.Fishes(bacteries) from depths of the ocean DO get what they require even there.How?They ARE there,so THEY DO know it well.In particular,they use sea weeds as we - food plus oxygen as we do.Their physiological need in both oxygen & good food is SO MUCH LOWER,& you can check it by the level of their life activities-very low too.The dencity of such a beings body imuch higher,meaning:more atoms in 1 santimeter cubic of the beings body comparing to a human one.Pressure is :more atoms in a cubic santimeter here-it spreads THERE,there being places with less atoms per cubic santimeter.So water(a dencer substance than our flesh) spreads into our bodies in depths to squash us like a nothing to death.The depths dwellers simply have more atoms per cubic santimeter in their bodies than the water that surrounds them,or just as dence as the water,so-they are reacting on depths just as we here react upon the air around us.Simply-they eat less calories per day & - they require less litres of oxygen per day to live,for this they HAVE to pay by the other side of the story- very low activity levels,like humans being in a letargic sleep state-we also would need MINIMUM of supply to be in letargy.Minimal amounts of both oxygen & sea weeds ARE there in the deep ocean waters,& so-they do EXIST(not live,but letargically sleep) there.Other questions are easier.Ask a bill maker-such projects would steal away half the money NOW from the rich US treasury.You gave a large question,now-get back an even larger answer,i am good here as well
