The rotifers (/ ˈroʊtɪfərz /, from Latin rota 'wheel' and -fer 'bearing'), sometimes called wheel animals or wheel animalcules, [ 1 ] make up a phylum (Rotifera / roʊˈtɪfərə /) of microscopic and near-microscopic pseudocoelomate animals.
Rotifer | Microscopic, Multicellular, Aquatic | Britannica
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.
Rotifer - Examples, Classification, Characteristics, & Pictures
Aug 27, 2024 · 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: Structure, Characteristics, and Classification
Rotifers are microorganisms that inhabit mainly freshwater aquatic environments and can range in size from 200 to 500 micrometers long. Rotifers are animals of the phylum Rotifera. They can be found mainly in freshwater within moist soils, still waters, and free-flowing waters.

Feb 28, 2021 · The rotifers are microscopic, multicellular, mostly aquatic organisms that are currently under taxonomic revision. The group is characterized by the rotating, ciliated, wheel-like structure, the corona, on their head. The mastax or jawed pharynx is another structure unique to this group of organisms.

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!”.

Oct 31, 2023 · The rotifers are filter feeders that will eat dead material, algae, and other microscopic living organisms. Therefore, they are very important components of aquatic food webs. Rotifers obtain food that is directed toward the mouth by the current created from the movement of the corona.
ADW: Rotifera: INFORMATION
Rotifers are considered broadly cosmopolitan, and are found in marine, brackish, and fresh waters throughout the world, excluding Antarctic. Several species are endemic to specific regions. (Brusca and Brusca, 2003; Segers, 2007) Biogeographic Regions. nearctic. native. …
10.1: Phylum Rotifera - Biology LibreTexts
About 2,200 species of rotifers have been identified. Figure 28.18 shows the anatomy of a rotifer belonging to class Bdelloidea. Some rotifers are dioecious organisms and exhibit sexual dimorphism (males and females have different forms). In many dioecious species, males are short-lived and smaller with no digestive system and a single testis.
