Protazoids are protazoan like organisms. These include not only DNA based organisims but GNA, TNA, and HDGTNA ones as well. These are classified as D-protazoids, and G-protazoids, for example, depending on their genetic basis. All prtazoids are unicellular eukaryotes whose cells have membrane-bound nuclei capable of mobility and heterotrophy. Protozoids are universally microscopic
Protozoids are ubiquitous throughout aquatic environments and the soil. Protozoids occupy a range of trophic levels – both as herbivores, decomposers, and predators upon unicellular organisms. Protozoids also play a vital role in controlling micro-flora and micro-fauna population and biomass. In turn, they are an important food source for microinvertebrates.
Some protozoids have the ability to form a cyst to protect it from harsh conditions, allowing it to survive exposure to extreme temperatures or harmful chemicals or without food, water, or oxygen for a period of time. For parasitic species the cyst will also enable it to survive outside of the host, allowing it to be transferred from one host to another. Individual protozoids are both male and female.
