The best description that fits a whale shark is a mouthful of teeth and constantly hungry stomach. Yes, it may seem morbidly appropriate yet it is not the truth. The fact is that, compared to other shark species, the whale sharks are far different.
In general, the whale sharks are deemed as filter-feeders. Mostly, they feed on plankton, red crab larvae, macro-algae, krill, small nektonic vertebrates, squids and even small fishes. Whale sharks possess unique oral anatomy which permits it to gulp in water, filter for food and expuse the water using its gills.
The whale sharks do not have big sharp teeth like other sharks do. The fact is, the size of their teeth is significantly smaller given that their teeth provide no real role when it comes to feeding. To put it differently, whale sharks do not chew up their food. They are filter-feeders as well as have a unique raking mechanism affixed within their gills which works as a filter to get food from the water they gulp in. Filter-feeding is somehow very interesting yet odd but logic.
Filter-feeding
As a substitute for preying on fishes, a whale shark sucks in mouthfuls of water loaded with planktons, tiny fishes and macro-algae. Afterward, it closes its mouth to catch the water inside of it, that is definitely funneled through the gill flaps, where water is gotten rid of. Any number of the food particles are jammed from the dermal denticles lining the whale shark's pharynx and gill plates. In order to sifter plankton, the whale sharks use their fine sieve-like contraptions. The measurement of these filters are 2-3 millimeters in diameter, prevent anything aside from water as well as smaller food particles from getting away.
Almost any organic material that is certainly stuck between the gill filters is ingested immediately after. At a human outlook, the notion of filter-feeding seems relatively difficult. You might find it not easy to understand employing your mouth like a sponge filter and swallowing the dirt that gathers up within the filter. Albeit whale sharks are somewhat well experienced in terms of filter-feeding, the problem involving it is simply not lost for them. These whale sharks are frequently reported to be coughing simply because they were not able to swallow all the food particles that are trapped in their gill filters. Eventually, the remaining particles there mount up and then block up the filters, making it not easy to eat without coughing and, most likely, choking.
These whale sharks feed actively. Contrary to many other species of sharks, or fishes as an example, whale sharks almost never stop eating. On the grounds that filter-feeding also doesn't need them to aquire for food, whale sharks may easily gulp in water no matter if they're resting in stationary position.
Some Other Filter-feeder Sharks
There are also two other filter-feeder sharks and they are the megamouth shark and the basking shark. The basking shark doesn't filter-feed the way in which whale sharks do. Rather than gulping as well as expelling water via their gills, basking sharks merely "basks," therefore forcing the water to circulate via their gills. The food particles are after that gathered as well as swallowed.
The truth is, whale sharks are varies greatly from what you firstly suspected them to be. Their teeth serve no purpose as they are filter-feeders; not to mention they do not have big pointy teeth.
