The rotifers (/ ˈ r oʊ t ɪ f ər z /, from Latin rota 'wheel' and -fer 'bearing'), sometimes called wheel animals or wheel animalcules, [1] make up a phylum (Rotifera / r oʊ ˈ t ɪ f ər ə /) of microscopic and near-microscopic pseudocoelomate animals.

Rotifers are multicellular animals with body cavities that are partially lined by mesoderm. These organisms have specialized organ systems and a complete digestive tract that includes both a mouth and anus. Since these characteristics are all uniquely animal characteristics, rotifers are recognized as animals, even though they are microscopic.

rotifer, any of the approximately 2,000 species of microscopic, aquatic invertebrates that constitute the phylum Rotifera. Rotifers are so named because the circular arrangement of moving cilia (tiny hairlike structures) at the front end resembles a rotating wheel.

2024年8月27日 · Rotifers, commonly known as wheel animals or wheel animalcules, are microscopic aquatic organisms belonging to the phylum Rotifera. The name ‘rotifer’ derives from a Neo-Latin word meaning ‘wheel-bearer’ due to their characteristic ciliated crowns that resemble rotating wheels. These cilia are used for both locomotion and feeding.

Rotifers are a type of microscopic, planktonic organism found in freshwater and brackish ecosystems all over the word. Their name comes from a Neo-Latin word meaning “wheel-bearer,” due to the distinctive crown of cilia used for swimming and feeding that look like rotating wheels.

Rotifers are microscopic aquatic animals of the phylum Rotifera. Rotifers got their name from the corona: a rotating, wheel-like structure covered with cilia at their heads. Rotifers also have a jawed mouth and complete digestive, sensory, and reproductive organ systems. They are “small,” but not “simple!”

2023年10月5日 · Rotifers, also known as wheel animals, are microscopic aquatic animals belonging to the phylum Rotifera. They get their name from the ciliated crowns located on their head, a characteristic structure used for both locomotion and gathering food particles.

Rotifers are animals of the phylum Rotifera. They can be found mainly in freshwater within moist soils, still waters, and free-flowing waters. Rotifers have a unique crown of cilia around their mouth which allows them to create a vortex current which helps them pull in their food.

2023年1月1日 · Rotifers (wheel animals) are widespread throughout the world (Fig. 6.1). They comprise a remarkably diverse group concerning their form, shape and species number, as well. More than 1000 species are known from Europe (Anon …
