Euglena Gracilis. People might say it looks like "Pea Soup".
It gets gets it energy from the sun or from eating other animals.
How they move around:
They move by twisting the flagellum in a way to pull it through water.
Where it hangs out:
They can be in fresh water pools, ponds and lakes.
Be on the look out,
They are a sort of combination of plant and animal!
It has a whippy tail called Flagellum.
