I appear in three different forms: merozoite, ookinete and sporozoite. I change forms at different stages of my life. Merozoites are oval shaped and have a single nucleus, a mitochondrion and some ribosomes. They also have rhoptries (in red). Ookinetes are zygotes that are elongated. They also have a nucleus but lack rhoptries. Sporozoites are much longer than merozoites but have similar structures.
I have a nucleus and I lack cilia and flagella so to move, I glide. I am able to enter host cells and live in the cytoplasm of this cell.
