More facts
Whale sharks are recognized as the world's largest fish. Whilst being large, widespread and easy to see, little is known about them from a scientific point of view. Many "facts" are based on speculation or estimates. The fact remains for now that much about the whale shark is mystery.
Even something as simple as the distinctive coloration raises questions. Whale sharks are a bluish or grey color with spots and horizontal and vertical stripes. Its belly is a creamy white. Why would a shark that spends much of its life feeding at the surface have these sorts of markings? One theory is that the whale shark’s nearest relatives are  bottom dwelling sharks that tend to use distinctive patterns as a form of camouflage. Another idea is that the pattern acts as a form of radiation protection, a theory which makes sense given that whale sharks spend so much time at the surface.
Another mystery is where whale sharks go. Are they migratory or do they just follow the areas where plankton is densest, following the movements of other pelagic which feed on similar food sources. Attempts have previously been made to track the whale sharks but the tags were also getting lost. This year, when researchers attempted to attach a webcam to a whale shark, they quickly found out why. Upon feeling attached to their dorsal fin, the sharks swam to the bottom, rolled around on the bottom until the camera was dislodged and then returned to the surface!
Due to the way that whale sharks feed, many people think that they are therefore similar to other plankton feeding animals, such as basking sharks. However, the whale shark does not need to move forwards to force food over its gills. Instead, they use a suction technique by opening their mouth, distending their jaw and then sucking. They then close their mouth to trap the plankton inside.
Inside their mouth, they have 300 rows of tiny teeth but these teeth do not appear to play a part in feeding. Instead, tiny teeth like structures known as dentals line the surfaces of the gill which effectively traps any animals bigger than about 2 mm in size. It is thought that not much other than water is allowed to escape out the gills. Feeding takes places in a vertical or near vertical position with the whale shark's head close to the surface. Feeding is often observed at dusk. For years there was great debate about how whale sharks reproduce. The dilemma was solved in 1995 when a whale shark was harpooned in Taiwan and 300 miniature whale sharks were discovered inside, ranging from about 40 - 60cm in length. This proved indisputably that whale sharks give birth to live young
