The monogononts (Monogononta) are a class of rotifers, found mostly in freshwater but also in soil and marine environments. They include both free-swimming and sessile forms. Monogononts generally have a reduced corona, and each individual has a single gonad, which gives the group its name. Males are generally smaller than females, and are produced only during certain times of the year, with females otherwise reproducing through parthenogenesis.

Males are generally smaller than females, and are produced only during certain times of the year, with females otherwise reproducing through parthenogenesis.
In monogononts key structures are represented by several types of (7 types of corona and 5 types of mastax) reflecting specificity of several types of locomotion and feeding.
Hetergonetic monogononts in their variability display diversity of morphological organization of the entire body; variability of bdelloids has a different character and concerns characters of the lower taxa (Fig.
The branches of bdelloids and monogononts that diverged at an early stage of their development differ in the rates of evolution, the terms of their history being relatively similar.
