Well a blue whale eats 40 million krill a day if that's what you mean't.
Various things attach themselves to whales, including lampreys and remoras. They don't feed off the whale, but rather use it as a means of transport.
They eat small fish which travel in schools, much like many whales. They swallow them whole and kill them by digesting them...
Many large predators can and will eat damsel fish.

It was not a whale. The book of Jonah clearly staes that Jonah was swallowed by a big fish, and a whale is not a fish. We are not told what sort of fish it was. It is quite conceivable that, for the time frame that the story was written in, it could have been likely that the "big fish" was in fact a whale. To many people, scientific classification and terms did not apply, and even though a whale is indeed a mammal, it swims and lives in the ocean, which could have possibly led many to believe that it was a big fish.
Jonah was in the stomach of a 'great fish' - assumed by many to be a whale - for three days and three nights.
An average whale eats 2,000 to 2,500 kilograms of food each day.

A bat is the only truly flying mammal, catches flying insects, and flies in the air, and roosts by hanging upside-down. Note, there are also bats species that only eats fruits, and some bats snatch small fish from just below the surface of rivers and lakes. A whale is also a mammal, but lives in the sea (which supports its huge weight, and eats krill (baleen whales) or fish and octopuses as with toothed whales. There are many other differences, too many to list here.
