Taxonomy
The Subkingdom Chromobiota is a member of the Kingdom Chromista. Here is the complete "parentage" of Chromobiota:
- Domain: Eukaryota
Whittaker & Margulis,1978 - eukaryotes
- Kingdom: Chromista
T. Cavalier-Smith, 1981 - Chromists
- Subkingdom: Chromobiota Cavalier-Smith, 1991
- Kingdom: Chromista
T. Cavalier-Smith, 1981 - Chromists
The Subkingdom Chromobiota is further organized into finer groupings including:
- Branch (1): Protostomia
- Infrakingdom (2): Haptista · Heterokonta
- Superphylum (1): Panarthropoda
- Phylum (7): Haptophyta · Hyphochytriomycota · Labyrinthulomycota · Ochrophyta · Oomycota · Opalozoa · Sarcodina
Phyla
Haptophyta
The haptophytes, classed either as the Prymnesiophyta or Haptophyta, are a of algae. The chloroplasts are pigmented similarly to those of the heterokonts, such as golden algae, but the structure of the rest of the cell is different, so it may be that they are a separate line whose chloroplasts are derived from similar endosymbionts.

Hyphochytriomycota
Labyrinthulomycota
Ochrophyta
Oomycota
Oomycetes also known as Water molds (or water moulds: see ) are a group of filamentous, unicellular Heterokonts, physically resembling fungi. They are microscopic, absorptive organisms that reproduce both sexually and asexually and are composed of mycelia, or a tube-like vegetative body (all of an organism's mycelia are called its thallus). The name "water mold" refers to their earlier classification as fungi, which stemmed from their preference for conditions of high humidity and running surface water, although they are now known to have evolved separately and show a number of differences. For instance, their cell walls are composed of cellulose rather than chitin and generally do not have septations. Also, in the vegetative state they have diploid nuclei, whereas fungi have haploid nuclei. [more]
Opalozoa
Sarcodina
Amoeboids are lifeforms that mainly consist of contractile vacuoles, a nucleus, and cytoplasm as their basic structure. They move and feed by means of temporary cytoplasmic projections, called pseudopods (false feet). They have appeared in a number of different groups. Some cells in multicellular animals may be amoeboid, for instance human white blood cells, which consume pathogens. Many protists also exist as individual amoeboid cells, or take such a form at some point in their life-cycle. The most famous such organism is Amoeba proteus; the name amoeba is variously used to describe its close relatives, other organisms similar to it, or the amoeboids in general. [more]
At least 1,633 species and subspecies belong to the Phylum Sarcodina.
