They are known to migrate every spring to the continental shelf of the central west coast of Australia. The fish prey consists of rays, tuna, and other sharks. Anything that doesn't pass through the gills is eaten.
This protection was introduced because of the possible serious impact that the fishery may be making on whale shark stocks. They are victims of bycatch, the accidental capture of non-target species in fishing gear.
Usually the sharks are more at risk from being struck accidentally by vessels whilst basking or feeding on the surface. However, it is considered not at risk in the Gulf of California. Skerry, Nat Geo Image Collection Read Caption Gentle giants, whale sharks filter-feed, swimming with their wide mouths open, collecting plankton and small fish.

The shark can process over gallons liters of water each hour. The skin of an adult whale shark can be as thick as 4 inches 10 cm and has the consistency of strong rubber, which limits possible predators to killer whales, great white sharks, tiger sharks and humans.
They scoop these tiny plants and animals up, along with any small fish that happen to be around, with their colossal gaping mouths while swimming close to the water's surface. Marine mammals include dolphins, whale carcasses, pinnipeds and whales.
Unlike most plankton feeding vertebrates, the whale shark does not depend on slow forward motion to operate its filtration mechanism. Tiger Sharks Diet True to its name, tiger shark is an apex predator and will feed on almost anything. The whale shark is a filter feeder, one of only three known filter feeding shark species, the other two being the basking shark and the megamouth shark.
It did not eat for the first 17 days, even though it swam constantly. Enter Your Email Address Below: Danger to Humans Generally considered harmless.
It is often seen offshore but commonly comes close inshore, sometimes entering lagoons or coral atolls. Greenland sharks are known to feed on hazelnut-sized snails. Often the whale shark is used as an indicator of waters rich in plankton-feeding fish that will, in turn, attract more valuable species such as tuna.Tracking the growth and diet of wild whale sharks over time is impractical, so Wyatt used a blood test to complement tissue isotope analyses.
Researchers take about 10 milliliters (2 teaspoons) of blood from one of the whale shark’s pectoral ancientmarinerslooe.com: Sciseek. “It's a great addition to knowledge of whale shark foraging and diet,” says Clare Prebble, a senior scientist with the Marine Megafauna Foundation.

The whale shark also eats eggs during spawning of other fishes and corals. Whale Shark Size: The whales are the largest animal found in the aquatic life.
Whale Sharks feed on wide variety of planktonic (microscopic) and nektonic (larger free-swimming) prey, such as small crustaceans, schooling fishes, and occasionally on tuna and squids. Also, phytoplankton (microscopic plants) and macroalgae (larger plants) may form a component of the diet.
Unlike most plankton feeding vertebrates, the whale shark does not depend on slow forward motion to. The whale shark diet is very unique considering the creature’s sheer size and presence in the ocean.
The whale shark is a filter feeder, one of only three known filter feeding shark species, the other two being the basking shark and the megamouth shark.
