Evolutionary Milestones
Animale-like protist passed the eukaryote milestone.
Habitat
There are four groups of animal-like protist: zooflagellates, sarcodines, ciliates, and sporozoans. Zooflagellates live in other animals. Sarcodines are found mostly in saltwater, but some species can be found in freshwater like streams. Ciliates can be found in aquatic environments and even in mud. Sporozoans are parasites that infect vertebrates and invertebrates.
Anatomical/Structural Features
Animal like protist have no cell wall. They contain a nucleus and a gullet for holding food.

How do they acquire nutrients
Animal-like protist are heterotrophs, which means must get their food rather than make their food.
What do they eat
Animal-like protist eat bacteria, algae, or other animal-like protist.
What eats them
Water fleas, flatworms, seed shrimp, clam shrimp and many other vernal pool invertebrates.
Symmetry
lack symmetry
Mobility
Zoo flagellates move by using their flagella. Sarcodines move by using an extension of known as a pseudopod. Ciliates move by using their cilia. Sporozoans do not move.
Reproduction
Zooflagellates, sarcodines and ciliates all reproduce asexually. Zooflagellates and ciliates reproduce by binary fission while sarcodines reproduce by cell division. Sporozoans reproduce both sexually and asexually.
Development
Animal-like protist do not have development steps, but their development includes the seven characteristics of life.
