Their feeding mechanism involves opening their mouths wide to create a suction-like effect, drawing in plankton, small fish, and other organisms. As they swim, water passes through their gills, extracting oxygen while the food particles get trapped by specialized filter pads.

Thus, the gills play a vital role in the respiration process of whale sharks, allowing them to thrive and survive in their oceanic environment.

Whale Shark Skeleton

Whale sharks do have gills. Being cartilaginous, their skeleton lacks bones and is flexible. This structure helps them adapt to their environment. Don’t be fooled by their immense size; whale sharks are filter feeders. They swim with their enormous mouths wide open, sucking in water which is then filtered through their gills.

The gill rakers, small structures in the gills, trap the plankton, tiny fish, and small crustaceans that make up their diet. This cartilaginous skeleton provides the flexibility required for the shark’s ability to suction feed effectively. So, while they may not have a bony skeleton like other fish, whale sharks have a unique cartilaginous structure that aids in their feeding adaptation.

Nothing short of fascinating!

Whale Shark Respiratory System: Breathing Underwater
