Detailed explanation-1: -Animal-like protists are commonly called protozoa (singular, protozoan). Most protozoa consist of a single cell. They are animal-like because they are heterotrophs, and are capable of moving. Although protozoa are not animals, they are thought to be the ancestors of animals.

Detailed explanation-2: -The Protozoa are considered to be a subkingdom of the kingdom Protista, although in the classical system they were placed in the kingdom Animalia. More than 50, 000 species have been described, most of which are free-living organisms; protozoa are found in almost every possible habitat.

Detailed explanation-3: -Animals like protists are often called protozoans. They include amoeba and paramecium.

Detailed explanation-4: -Animal-like protists are also known as Protozoa. Some are also parasites. The Protozoa is often divided into 4 phyla : Amoebalike protists, flagellates, ciliates, and spore-forming protists.

Detailed explanation-5: -Rhizopoda (animal-like protists having “false feet” called pseudopodia) Ciliates (protists covered in the tiny hairlike cilia) Flagellates (protists having whiplike “tails”) Sporozoa (parasitic protists)
