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.
Actually, these friendly giants, the whale sharks are known as filter-feeders. What thay mainly feed on are red crab larvae, krill, plankton, small nektonic vertebrates, squids, macro-algae and small fishes. The whale sharks can gulp in water, filter for food and expulse the water using its gills owing to its unique oral anatomy.
Unlike other sharks, the whale sharks don't have big sharp teeth. In actual fact, the size of their teeth is somewhat smaller seeing that their teeth provide no real use as part of feeding. To paraphrase, whale sharks never munch their food. As filter-feeders, these mentioned whale sharks possess a unique raking mechanism attached in their gills which serves to filter food from the water they gulp in. Their filter-feeding characteristics makes their diet interesting, 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.
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.
Many Other Filter-feeder Sharks
The basking shark as well as megamouth shark are among the shark species that filter-feeders. The basking shark doesn't filter-feed the manner in which whale sharks do. As an alternative to gulping and also expelling water thru their gills, basking sharks basically "basks," hence forcing the water to circulate by using their gills. The food particles are in that case accumulated and also swallowed.
Actually, whale sharks are completely different from what you initially believed them to be. They do not use their teeth as they are filter-feeders and they do not have mouthful of sharp teeth.
