The whale shark (Rhincodon typus) is the largest fish in the ocean, known for its distinctive checkerboard pattern of spots and stripes. It inhabits warm tropical waters and is a filter feeder, mainly consuming plankton. Despite its size, it is known for its gentle nature.

The Rhincodon typus, commonly known as the whale shark, is native to all tropical and warm-temperate seas. It is found across the globe in the Atlantic, Pacific, and Indian Oceans. This species primarily inhabits open waters but can often be found in coastal regions where there are abundant planktonic food sources.

Whale sharks prefer warm waters, generally staying in sea temperatures ranging from 21 to 25 degrees Celsius (69 to 77 degrees Fahrenheit). They are often found in both pelagic (open ocean) and neritic (coastal) zones, and have been observed at depths ranging from the surface to at least 1,928 meters (6,325 feet).

As filter feeders, whale sharks play a crucial role in the marine ecosystem by consuming large quantities of plankton and small fish, thus helping to maintain the balance of plankton populations. They are known to follow plankton blooms, and their presence is often an indicator of high plankton abundance in the area.
