Hexarthra is identified by its mastax possessing malleoramate trophi, with the number of teeth on the uncus serving as a taxonomy criterion. The morphological traits, such as size, the ratio of ventral arm to body length, number of bristles, and number of teeth on the uncus, vary significantly under different environmental conditions. There is an observed trend towards an increase in the number of teeth on the uncus with rising salinity, while the ratio of ventral arm to body length tends to decrease in warmer climates. Despite this variability, the four species within this genus can be distinguished based on the number of teeth and exhibit distinct ecological preferences. Hexarthra typically possesses six robust, muscular, and setose appendages, with a conical body structure. It features a double ciliary wreath and a ciliated groove, earning it the nickname “jumping rotifer.” These organisms are commonly found in small alkaline lakes and ponds during the summer season.
