Mollusca, meaning âsoft-bodied,â is one of the largest phylums in the animal kingdom. The word mollusc (or mollusk) derives from the Latin word âmollis,â which means âsoft.â There are an estimated 200,000 species of mollusk worldwide accounting for nearly a quarter of all marine life.Familiar phylum species include snails, squid, octopuses, clams and oysters.ephalopods. The 600 to 650 species of cephalopod inhabit the sea, including squid, octopuses, and cuttlefish. Most lack the shell of other mollusca, but have tentacles that propel them through the water using suction.
The molluscs or mollusks /ËmÉlÉsks/ compose the large phylum of invertebrate animals known as the Mollusca. Around 85,000 extant species of molluscs are recognized. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms.Numerous molluscs also live in freshwater and terrestrial habitats.They are highly diverse, not just in size and in anatomical structure, but also in behaviour and in habitat. The phylum is typically divided into 9 or 10 taxonomic classes, of which two are entirely extinct.he brain, in species that have one, encircles the esophagus. Most molluscs have eyes, and all have sensors to detect chemicals, vibrations, and touch. The simplest type of molluscan reproductive system relies on external fertilization, but more complex variations occur.
