How Do Mollusca Feed
How do mollusca feed? The phylum mollusca feed very uniquely as measured by how they are one member of the animal kingdom that is ecologically successful. As the phylum mollusca includes some of the most familiar animals, such as snails, clams, mussels, squids, and fifty thousand species of mollusca have been discovered that brought about the diversity of a rich fossil record. They have such one of a kind way of how to feed themselves like hiding themselves in the crack of the rocks during the day and come out to feed at night.
How do mollusca feed? Is a question, which for some people are not relevant to know for reasons that the appearance and the use of the phylum mollusca is enough for them to be entertained? But it is important to appreciate and learn the fact of how do mollusca feed because upon learning how they do feed will forewarn you that not all phylum mollusca are edible but sometimes not safe to eat them as a raw food. The phylum mollusca as explained earlier include many kinds of seafood materials available in the market and they are favorite seafood of everyone. Most of the dietitians advise that these seafood’s are good for the health, regardless of what is your race, religion and belief, the snails and clams are good food.
How do mollusca feed? This is the reason why the mollusca feed themselves very exceptional because its digestive tract is complex. The foregut region consists of an esophagus and a mouth cavity, which contains a toothed belt called the radula, found in almost all mollusks and peculiar to the phylum. The radula is usually used for scraping food, such as algae, from surfaces. The number and form of radula teeth are highly variable; some species have a single radula tooth while others may have several hundred thousand. In some the teeth are hollow and poison containing and are used as weapons; other radula modifications exist. Most molluscs have that radula. The radula that looks like a firm ribbon-like structure made of protein-chitin, covered with sharp teeth. The radula which is usually used for feeding can also be modified in amazing ways like to rasp, grate, grasp, cut, stab and inject poison. For example, drills are snails that use their radula to make a hole through their hard-shelled prey. The stomachs of mollusks are generally complex, and these, too, differ with the species and according to the feeding habits of the animal.
How do mollusca feed? The mollusca on the seas are safe to be taken as food because not unless the waters are not contaminated we are sure that they take good algae’s as their primary food. By then it is also safe for people to eat them. However the mollusca found in the non-salty waters or snails in living on the dry land are not safe as food because the radula can just pick any dirt to feed them. That is the main cause why people eating snails from the non-salty waters get the bacteria of scistosomiasis, which is one of the high killing diseases in rural area. Whatever would it be the mollusca family is in danger that in the near future we are losing them. Like other marine creatures, molluscs are vulnerable to habitat loss due to reclamation or human activities along the coast that pollute the water. They are also vulnerable to over-collection for food and for the diverse use of their body coverings, the shell.
