Wow so many questions!! Ok lets start with the first one, why is it that we float and fish don't. Well, it's got a lot to do with body tissue. You see, fat floats, and humans have comparatively more fat than a fish. Some fish also have a "swim bladder", it's kind of like a balloon in their belly, when they want to float they fill it with gas, and when they want to sink they let it shrivel up. Next question, if there is no light in the benthic region of the ocean, why would some of the organisms be bioluminecent and what advantage does that serve? Well, it is because there is no light that they are bioluminescent! You see thanks to light you can see other people and communicate with them, a lot of organisms in that live in the dark communicate by flashing lights at each other. Next question, and what do organisms living within this region feed on? There are lots of different organisms that live in this region, and they all have vastly different feeding habits. Some of them feed on the algae that lives on the bottom, some filter feed by waving tiny hairs in the water to grab at small food particles and all sorts of things. And finally, And what is the deepest living organism that has been found? Well the only information I could find was on deepest fish found, and that was at 27,460 ft (8370m). Pretty deep huh! Well, I hope I answered everything, phew.
