Mollusks are among the most diverse and abundant animal groups, inhabiting many aquatic and terrestrial environments. They are important ecosystem engineers, helping to structure aquatic bottom environments and providing habitat, protection, and food to a wide array of other taxa.

What are economic importance of molluscs?
Many gastropods, bivalves, and cephalopods are a source of food for many cultures and therefore play an important role in the fishing industries of many countries. In addition to their economic value as food, mollusks are also used to make jewelry the most notable and valuable example of which is pearl jewelry.
What ecosystem do mollusks live in?
Mollusks live in most terrestrial, freshwater, and marine habitats. However, the majority of species live in the ocean. They can be found in both shallow and deep water and from tropical to polar latitudes. Mollusks are a major food source for other organisms, including humans.
What are examples of the ecological and economic importance of molluscs?
Many marine molluscs are part of a common human diet, like octopus and squid, very appreciated in the East, and oysters and mussels, consumed all around the world. Besides molluscs that are part of the food industry, pearls made by oysters have high commercial value.
What are some of the economic and medical importance of mollusks to man?
Molluscs and humans are most often associated economically. ... In freshwater habitats molluscs may serve as intermediate hosts for parasites such as digenetic trematodes and are an integral part of the Schistosomiasis contagion that infects millions in the tropical regions of the world.
How do molluscs adapt to their environment?
Molluscs on the rocky shore are mostly univalved (one shell). They cannot burrow into sand like the bivalves for safety so they have very strong shells with an operculum (trapdoor attached to the foot muscle). Limpets are a good example of this. They are particularly well adapted for life on rocky surfaces.
What does Mollusca mean?
: any of a large phylum (Mollusca) of invertebrate animals (such as snails, clams, or squids) with a soft unsegmented body usually enclosed in a calcareous shell broadly : shellfish.
What is the characteristics of phylum Mollusca?
The animals belonging to the phylum Mollusca have soft-bodies, triploblastic and bilaterally symmetrical and coelomate. The study of Mollusca is called Malacology. They are sluggish invertebrates, with a thin fleshy envelope or mantle covering the visceral organs.
What does ecology deal with?
Ecology is the study of organisms and how they interact with the environment around them. An ecologist studies the relationship between living things and their habitats.
Why do molluscs have shell?
As the mollusk ages, the shell becomes thicker and sturdier. As such, older mollusks usually have strong shells. The primary purpose of the shell is protection. It protects the animal against predators and guards the internal organs.
How does phylum Mollusca play a role in cultural uses?
Practical interactions with molluscs range from their use as food, where species as diverse as snails and squid are eaten in many countries, to the employment of molluscs as shell money and to make dyestuffs and musical instruments, for personal adornment with seashells, pearls, or mother-of-pearl, as items to be ...
What is economic importance of phylum Arthropoda?
Arthropods contribute to human food supply, pollinate crops, help maintain ecosystem sustainability by biologically suppressing destructive arthropods, but cause and transmit diseases to humans and livestock and incur crop losses.
How does a Mollusca move?
Most mollusks move with a muscular structure called a foot. The feet of different kinds of mollusks are adapted for different uses, like crawling, digging, or catching prey. ... These are mollusks like snails and slugs that have just one shell or no shell at all. Gastropods creep along on their broad foot.
How do molluscs survive?
On way that mollusks protect themselves is to build a hard shell around their bodies. Clams, oysters, snails, mussels, and scallops all have shells. As long as the shell is not broken, it is hard for other animals to eat them. Another way that mollusks protect themselves is through camouflage.
Why are mollusks so successful?
If success is measured in terms of number of species and variety of habitats to which they have become adapted, then molluscs are one of the three most successful groups in the animal kingdom. ... Molluscs have evolved a distinctive and highly successful body plan that features a mantle, shell, muscular foot, and radula.
