Water Pressure Humans can travel three to four atmospheres down in the ocean and be ok.

How far can a human travel into the sea? There have only been eight divers that have traveled further than 800 feet below sea level
Aquatic Organism Adaptations Some aquatic organisms create light by using a chemical process called bioluminescence
