Submersible with lights on in the deep ocean

Deep ocean

The deep ocean begins where the continental shelves and their shallow waters give way to the dark depths where little or no sunlight penetrates. Here, in the layer underneath the sunlit open oceans, live some of the most bizarre and highly adapted creatures on the planet. With no plants or algae here to photosynthesize and form the base of the food chain, life here is largely dependent on the dead material and droppings that sink down from above.
