Os Opisthokonta são organismos eucariotas que formam um clado estritamente monofilético (um ramo evolutivo) no qual coexistem algumas formas unicelulares flageladas, inclui os reinos dos fungos verdadeiros ( Fungi) e dos animais verdadeiros ( Animalia ).
Opisthokont characteristics include synthesis of extracellular chitin in exoskeleton, cyst/spore wall, or cell wall of filamentous growth and hyphae; the extracellular digestion of substrates with osmotrophic absorption of nutrients; and other cell biosynthetic and metabolic pathways.

The apicomplexan protists are so named because their microtubules, fibrin, and vacuoles are asymmetrically distributed at one end of the cell in a structure called an apical complex (Figure 28.8.6 28.8. 6 ). The apical complex is specialized for entry and infection of host cells. Indeed, all apicomplexans are parasitic.
Ichthyophonida. Synonyms. Mesomycetozoa Mendoza et al., 2002. The Ichthyosporea (or DRIP clade, or Mesomycetozoea) are a small group of Opisthokonta in Eukaryota (formerly protists ), mostly parasites of fish and other animals.

Choanozoa is a clade of opisthokont eukaryotes consisting of the choanoflagellates (Choanoflagellatea) and the animals (Animalia, Metazoa). The sister-group relationship between the choanoflagellates and animals has important implications for the origin of the animals.
Opisthokonts are a superkingdom of the Eukaryota, including the animals and fungi. It is a group of unikonts . There are several classifications of the eukaryotes which are being discussed. Each of them divides the domain Eukaryota into five groups, but there is disagreement on the details. [4]
