Why does most of the ocean life live in or at least visit the ocean surface?  

• that is where the majority of the oxygen and sunlight occurs
• that is where chemo-synthesis occurs and therefore more life
• the water pressure is higher there and is more enjoyable
• the temperatures are colder and most animals need cooler temperatures

Organisms that live on the bottom of aquatic ecosystems are known as 

• littoral 
• benthic 
• nekton
