Lesson plan
Halteria
Halteria, sometimes referred to as the jumping oligotrich, is a genus of common planktonic ciliates that are found in many freshwater environments. Halteria are easy to locate due to their abundance and distinctive behaviour with observations of Halteria potentially dating back to the 17th century and the discovery of microorganisms. Over time more has been established about their morphology and behavior, which has led to many changes in terms of classification. Species of Halteria can exist in both a trophic and an encysted form but are most commonly described in the trophic form. Species of Halteria can be identified by their unique jumping movement which is enabled by an equatorial row of stiff cirri that beat in unison, allowing the organism to move very quickly backwards. Members of the genus Halteria are heterotrophic and serve as important bacterivores in the habitats they occupy as well as being preyed upon primarily by metazoans. One paper published on December 27 2022 identified Halteria sp. as the first identified "virovore", an organism that can feed on virus. The cells of Halteria are roughly dome shaped and in addition to the equatorial cirri, they possess a collar of cilia around the buccal opening used for feeding and locomotion.…
