Whale Shark Quiz – The Gentle Giant That Filters Plankton

The whale shark is the largest living fish, growing over 12 meters long. Despite its size, it feeds mainly on plankton and small fish, filtering them from the water with special pads. Its thousands of tiny teeth play no real role in feeding.

Each whale shark has a unique pattern of spots, and researchers identify individuals from photos using an algorithm adapted from tools for matching star patterns.

Whale sharks gather at places such as Ningaloo Reef in Australia, Donsol in the Philippines and Isla Holbox in Mexico. Pups hatch from eggs inside the mother, and the species is listed as Endangered.
