Protoctists (Protoctistae)

All the eukaryotic single-celled microrganisms previously labelled protista (protozoa and protophyta), but also certain multi-celled organisms, such as kelp, that don't belong to the plant, animal or fungi kingdoms. There are known to be thousands of species of these organisms, all of them aquatic: they include the amoebas, algae, seaweeds, slime molds, ciliates, diatoms, paramecia, forams and many others.
