Species Feature: Whale Shark

Growing to lengths of up to 12 metres, the Whale Shark is the world’s largest fish! Their mouths can grow to widths of 1.5 metres too! Harmless to humans, these gigantic fish eat plankton and small fish by drawing water through their gills. 

In Autumn each year at the Ningaloo Marine Park, the incredible mass spawning of coral takes between seven and 10 days after the full moon in March and April. This event triggers the arrival of krill and plankton, which in turn creates a feeding frenzy for numerous fish species, including the Whale Shark. They are sometimes observed hanging vertically with their mouths open on the water's surface, allowing water and food to pour in!

Despite gathering in schools of up to 100 individuals, Whale Sharks are generally solitary animals. They are usually found in the tropical waters around Australia, however as the water temperatures increase in the summer, they venture further toward Austalia's south-eastern and western coastlines. 

One would expect such a large 'shark' to be fast and agile in the water, however, these gentle giants are slow and leisurely swimmers who cruise at speeds of no more than 5 km per hour (or 3.1 miles per hour)!
