The Magical Uknown World of Mollusca - Hanya Awan

Many individuals do not learn about how animal classification works and how scientists use the binomial nomenclature system to understand and discover new animals every single day, whether they are known species or known but not found that have been searched for many years and decades. The phylum Mollusca is a very distinct phylum from the rest of the Animalia groups because these animals are one of the smartest creatures to exist underwater. In fact, mollusks are extremely diverse invertebrate animals with a rich fossil record, highly divergent life cycles, and considerable economical and ecological importance. Some key species and groups include those of worms like aplacophorans, armoured groups (such as polyplacophoras, gastropods, and bivalves) and the highly complex cephalopods.

The phylum Mollusca is extremely distinct from other phyla because molluscan origins and evolution for their phenotypes have largely remained unresolved, though significant progress has been made over recent years. Gene expression data indicate key regulators involved in anterior-posterior (front and back) patterning (the homeobox‐containing Hox genes) lost this function and were co‐opted into the evolution of taxon‐specific novelties in conchiferous. Haven has taken over most areas on Earth which include terrestrial and aquatic habitats on Earth, mollusks are among the best-known animals on the planet. Unfortunately, due to exploitation, their population has been at a steady pause because of heavy demands for sources of food [snails, mussels, clams, squids, octopuses, etc.] or jewelry and accessory use [these include pearls being taken from mollusks and used for jewelry]. Amidst the mass exploitation, recent research has indicated that these animals may hold the future for ending the life-lasting effects of deadly diseases such as cancer. They have been used in medical labs for additional research and for general biomedical applications [for example toxins from cone snails in the treatment of neural diseases such as epilepsy, Parkison’s Alzheimer’s or pain management. Mollusks also hold the greatest diversity compared to any other phyla. They have a wide range and almost unmatched diversity of molluscan morphological phenotypes that are exemplified by key representatives such as gastropods (which includes snails and slugs), bivalves (clams and mussels), and cephalopods (nautiluses, squids and octopuses) but can also include enigmatic and complicated groups such as spicule-bearing simple worms (the alpacophorans). Mollusks have adapted to almost every habitat on Earth except for air (atmosphere). Although they are usually marine species, bivalves and gastropods include freshwater species that live fully in terrestrial existence. Furthermore, some gastropods have maintained an adaptation to living on land, with thousands of species living fully terrestrial existence. Often discovered on rocky, sandy and muddy substrata, mollusks burrow, crawl and become cemented to the surface or are generally free-swimming. Mollusks are found around the world, but there is a preponderance of certain groups in certain regions. By closely associated with their food sources, many molluscan groups are limited geographically due to their reliance on specific food supplies (e.g., plants or herbivores) or participation in food chains; for example, bivalves in the family Teredinidae (shipworms) are associated with wood. The diversity of species in cold-water regions is generally lower. To conclude, governments should see the ecological benefits of their territory and how mollusks can bring potential support to humans in many ways with more efficiency and less costly projects.
