Question

What are soft bodied shelled animals?Note down their distinguishing features.

Answer 1

Dear Student,

Soft-bodied organisms are animals that lack skeletons, a group roughly corresponding to the group Vermes as proposed by Carl von Linné. All animals have muscles but, since muscles can only pull, never push, a number of animals have developed hard parts that the muscles can pull on, commonly called skeletons. Many of them serve as food to human beings. The secretion of so-called mucus gland is used as a source of dyes. Their shells are used in preparing buttons and ornaments
