People Who Make প্রশ্ন About What They Are Eating.............................................................................................................................................................................................Just Kidding XD(Probably).

It Really Depends If The Creature Is A Herbivore,A Carnivore অথবা An Omnivore.
If It's The First Then Sea Plants And Phytoplankton.
If It's The সেকেন্ড Then Other Creatures.
If It's The Last Then Pretty Much Everything It Finds !!!!

I think that they eat the idea of মাছ in a theoretical ocean.
