Whale sharks are filter feeders, meaning they feed by filtering small organisms from the water. Their diet consists primarily of plankton, small fish, squid, and crustaceans. Whale sharks are known for their large mouths, which can be up to 5 feet (1.5 meters) wide, allowing them to take in large amounts of water and filter out their prey. They have over 3,000 tiny teeth, but these are not used for chewing, but rather for holding their prey in their mouths.
Water
Whale sharks are able to drink seawater, but they do not need to drink as much water as other marine animals because they get a significant amount of water from the food they eat. They primarily obtain water through their diet of plankton and other small organisms, which contain a high amount of water.
