Protozoa are classified as invertebrates. They are single-celled organisms that belong to the kingdom Protista and do not have a backbone or spinal column, which distinguishes them from vertebrates. Protozoa can be found in various environments and exhibit diverse forms and functions, but they lack the complex structures associated with vertebrate animals.
