A mouthful of teeth and a constantly-hungry stomach is the best description to fit the whale shark. Though the description might be fitting yet it has nothing to do with the real truth. In reality, in terms of diet, the whale sharks are very different from other sharks.
The Whale Sharks are actually viewed as filter-feeders. They chiefly feed on plankton, krill, macro-algae, small nektonic vertebrates, small fishes and squids. A unique oral anatomy is possesed by the whale sharks which enables it to filter for food, gulp in the water and expulse water through 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
In lieu of preying on fishes, a whale shark sucks in mouthfuls of water abundant with macro-algae, tiny fishes and plankton. And then, it closes its mouth to catch the water inside of the body, which happens to be funneled through the gill flaps, where water is removed. Almost all of the food particles are stuck against the dermal denticles lining the whale shark's pharynx and also gill plates. They use their fine sieve-like contraptions to sifter plankton. The diameter of these filters are only 2-3 millimeters, prevent anything besides water and also smaller food particles from getting out of.
Virtually any organic material that's trapped between the gill filters is ingested right after. To the human viewpoint, the idea of filter-feeding seems somewhat difficult. You will probably find it tough to comprehend utilizing your mouth like a sponge filter as well as swallowing the dirt which builds up within the filter. Despite the fact that whale sharks are really well experienced when it comes to filter-feeding, the problem associated with it isn't lost for them. Oftentimes, the whale sharks are reported coughing as they are not able to swallow all the food particles stuck in their gill filters. Soon enough, the remaining particles there build up and also obstruct the filters, making it hard to eat without the need of coughing and, perhaps, choking.
Did you know that the whale sharks ar active feeders?. In contrast to some other shark species, or fishes for instance, whale sharks hardly ever give up eating. Due to the fact that filter-feeding also doesn't need them to run after for food, whale sharks can easily drink in water even if they're resting in stationary position.
Various 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.
