As it swims with its mouth open, it sucks masses of water filled with prey into its mouth and through spongy tissue between its 5 large gill arches. After closing its mouth, the shark uses gills rakers that filter the nourishment from the water.

What is a fun fact about whale sharks?
They can process more than 6,000 litres of water an hour through their gills. Although its mouth can stretch to four feet wide, a whale shark’s teeth are so tiny that they can only eat small shrimp, fish and plankton by using their gill rakers as a suction filter.
Do whale sharks drink water?
Unlike bony marine fish, sharks don’t drink water. Sharks absorb (pure) water from the sea by osmosis. Osmosis is a process in which water flows across a semi-permeable membrane from an area of higher concentration of water to an area of lower concentration of water, effectively moving to equalize concentrations.
What are whale sharks adaptations?
The whale shark is well adapted to its environment. Its monumental size is its greatest protection and adults have little to fear from natural predators except for humans. It has a very efficient feeding mechanism and its somewhat opportunistic diet provides a broad base of food supply.
Do whale sharks have tongues?

Even though they are huge, whale sharks feed on tiny plankton, small fish, and crustaceans. They feed by gulping mouthfuls of water and forcing that water through their gills. Prey gets trapped in dermal denticles and a rake-like structure called the pharynx.
How much water does a whale shark process in an hour?
A whale shark can process more than 6,000 liters of water an hour through its gills. The whale shark is found in open waters of the tropical oceans and is rarely found in water below 70 degrees Fahrenheit. Whale sharks can be found in all temperate and tropical oceans around the world except the Meditteranean Sea.
