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.

Cercozoa. Retaria. Les Opisthocontes ( Opisthokonta) sont un groupe d' eucaryotes unicontes regroupant des organismes très divers en apparence, résultant du rapprochement récent de plusieurs taxons, dont les champignons et les métazoaires.
Los opistocontos ( Opisthokonta) son un clado de organismos eucariotas en el que coexisten algunas formas unicelulares flageladas ( coanozoos) junto a los hongos verdaderos ( Fungi) y animales verdaderos ( Animalia ). 3 4 5 6 7 El nombre alude a que el flagelo, singular cuando está presente, ocupa una posición posterior, avanzando la c...
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]
