On the Ningaloo Reef in Western Australia from April until July the world's largest fish inhabbit the waters along the coast.
Whale Shark (Rhiniodon Typus)
This fish, the largest of the shark family and the largest fish in the world, is a harmless plankton eater. Reported to reach 18 metres (60ft) but averages 12 metres (40ft) in length, the whale shark is easily identified by its huge size, wide mouth and distinctive pattern of white spots.
Thought to mainly inhabit worldwide temperate and tropical seas, it is rarely seen in shallow coastal waters, but is a daily visitor to the Ningaloo Reef every year between late March to June or July when up to 12 whale sharks have been spotted close to the reef feeding on the plankton in the nutrient rich waters.
It is an incredible swim to glide alongside these gentle giants. The first time you see the amazing mouth and those spots you'll never forget.
Whale Shark tour operators have airplanes in the sky to guide them to the sharks and the snorklers go in (max. 10 at a time) and swim with the shark untill it dives down again. You are not allowed to touch them.
