What type of protists is Giardia Lamblia in?

Giardia lamblia is classified as a protozoan, which is a diverse group of microscopic, eukaryotic organisms that include not only protozoans but also unicellular algae and slime molds. Protozoans are distinguished from bacteria and fungi by their more complex cellular structure and typically greater mobility. Specifically, Giardia lamblia is a flagellate protozoan, meaning that it possesses one or more whip-like structures called flagella for movement.
