Mollusca is a phylum of protostomic invertebrate animals, whose members are known as molluscs or mollusks[b] (/ ˈmɒləsks /). 86,600 extant species of molluscs are recognized [6], making it the second-largest animal phylum after Arthropoda.
Mollusks or Molluscs are a group of soft-bodied invertebrates distributed across marine, freshwater, and terrestrial habitats. They belong to the phylum Mollusca, the second largest after Arthropoda, with around 76,000 extant species worldwide, accounting for around 23% of all marine species. The phylum derives its name from the Latin word mollis, which means ‘soft,’ referring to their ...
MOLLUSCS Mollusca is the group of animals that includes gastropods (snails, slugs, limpets etc), bivalves (clams, oysters, mussels etc), cephalopods (octopuses, nautiluses, squids etc), scaphopods (tusk shells), caudofoveates, solenogastres, monoplacophorans and polyplacophorans (chitons).
The rapid origin of so many different kinds of animals, including mollusks, is an event popularly known as the Cambrian Explosion or Early Cambrian Transition. One animal that may have been among the very first molluscs is Kimberella, a gastropod-like animal from the Ediacaran period. The classification of this group is debated among ...
Molluscs are a clade of organisms that all have soft bodies which typically have a "head" and a "foot" region. Often their bodies are covered by a hard exoskeleton, as in the shells of snails and clams or the plates of chitons. A part of almost every ecosystem in the world, molluscs are extremely important members of many ecological communities.
