Answer Details
Flatworms and roundworms are said to be invertebrates because they have no backbones. Invertebrates are animals that lack a vertebral column or backbone. This distinguishes them from vertebrates, which have a backbone composed of individual vertebrae. Flatworms and roundworms are both examples of invertebrates, as they lack a backbone. Their small size, ability to live inside other organisms, or unicellularity do not determine their classification as invertebrates.
