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.
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.

De Wikipedia, a enciclopédia encyclopedia. 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 ).
These protists exist in freshwater and marine habitats, and are a component of plankton, the typically microscopic organisms that drift through the water and serve as a crucial food source for larger aquatic organisms. Figure 28.8.4 28.8. 4: The dinoflagellates exhibit great diversity in shape.
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]
