Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda. The members are known as molluscs or mollusks. Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species.
Mollusks are animals with soft bodies. A huge group of them have external shells just like snails and clams. Each of them has unique characteristics; however, it is because of their body plan that they are all considered as mollusks.
