Diet and Feeding

Diet and Feeding

Whale sharks are fascinating creatures that are known for their massive size and gentle nature. These gentle giants are filter feeders and consume tiny organisms that are present in the water column. Whale sharks are considered to be plankton feeders, as they consume krill, plankton, and small fish.

Whale sharks feed on a variety of organisms that are present in the water column. Their diet primarily consists of zooplankton, phytoplankton, and small fish. These animals are abundant in areas where whale sharks are found, such as the tropical coastal waters of the Western Pacific Ocean.

The diet of whale sharks changes with their age and size. Juvenile whale sharks consume a higher percentage of fish compared to phytoplankton and zooplankton. During these years, they typically feed on small fish, squid, and crustaceans. As they grow older and larger, they start to consume more planktonic organisms.

Whale sharks are filter feeders, using their large mouths to take in massive amounts of water that they filter through their gills. The tiny organisms that they feed on get stuck in their gill rakers, which they then consume.

How do they feed?

Whale sharks are passive feeders and rely heavily on the movement of the water to bring their food to them. They have been observed feeding at the surface, but they generally feed at depths of around 200 meters.

Whale sharks have an efficient feeding mechanism that allows them to consume large amounts of food quickly. They can filter up to 6,000 liters of water per hour and can consume up to 21 kilograms of food in a single day.

One of the most interesting things about whale sharks is that they can also feed cooperatively. They have been observed feeding in groups, where they collectively push a school of fish towards the surface and then take turns feeding.

In conclusion, whale sharks have a diverse diet and feed on a variety of organisms that are present in the water column. They are filter feeders that consume large amounts of water and food, making them one of the most efficient feeders in the animal kingdom. Whale sharks play a crucial role in maintaining the balance of the marine ecosystem and are a fascinating species to study. As the largest fish in the sea, whale sharks need our protection, and it is important to promote sustainable ecotourism practices to ensure their survival.
