What do most fish eat on the ocean floor?

Filter feeding animals include animals like bivalves, tube worms, sponges, and even large animals like baleen whales and manta rays.
How do deep sea fish get food?
In the absence of sunlight, most animals in the deep ocean (below 200 m) are reliant on detritus from the surface waters as their primary source of food. This is mainly composed of dead plankton and fecal pellets produced by zooplankton, which are exported to the deep seafloor as fine particles of ‘marine snow’.
What is food for many deep sea creatures?
