Detailed explanation-1: -Most invertebrates can move. Even sponges move when they are very young and very small. Once they settle down they don’t move anymore. Other invertebrates like lobsters and insects move around their whole lives.

Detailed explanation-2: -Some ocean invertebrates crawl and burrow in the mud; others simply float or drift wherever the currents take them; and some anchor themselves to the ocean floor and do not move around at all. Some microscopic dinoflagellates move by waving tiny, whiplike flagella.

Detailed explanation-3: -One of the noticeable differences between vertebrates and invertebrates is their size. Invertebrates, such as worms, shellfish, and insects, are small and slow-moving because they lack effective ways to support a large body and the muscles needed to power it.
