Yes. The whale shark's diet is extremly vaired, their favourite
meal is plankton.They scoop these tiny plants and animals up, along
with any small fish that happen to be around, with their colossal
gaping mouths while swimming close to the water's surface.
The whale shark, like the world's second largest fish, the
basking shark, is a filter feeder. In order to eat, the beast juts
out its formidably sized jaws and passively filters everything in
its path. The mechanism is theorized to be a technique called
"cross-flow filtration," similar to some bony fish and baleen
whales.
