What is a rotifer classified as?
Also referred to as “wheel animals/wheel-bearer”, Rotifers are tiny, free-living, planktonic pseudocoelomates that make up the phylum Rotifera.
What kingdom does rotifer belong to?
Animal
Rotifers/Kingdom
Why is a rotifer not a protist?
The Rotifer is not a protist, but part of the Kingdom Animalia. View more pond water animals here. Rotifers (Rotifera) are microscopic animals with about 1,000 cells. There is a well-developed cuticle which may be rigid, giving the animal a box-like shape, or flexible, giving the animal a worm-like shape.
Is a Rotifera decomposer?
Nematodes are tiny, cylindrical, often transparent microscopic worms, and are the most abundant of the physical decomposers. Members of Phylum Rotifera are called ROTIFERS. Many rotifers are tiny, transparent, free-living animals that are mostly found in fresh water.
How do I identify my rotifer?
The two most distinctive features of rotifers (in females of all species) are the presence of corona on the head, a structure ciliated in all genera except Cupelopagis and presence of mastax.
Do rotifers have immune system?
Innate immune system of bdelloid rotifers.
Do rotifers cause disease in humans?
There are no known adverse effects of rotifers on humans.
Is rotifer a virus?
A cytoplasmic dsRNA virus, rotifer birnavirus (RBV), has recently been isolated from the rotifer Brachionus plicatilis and is associated with a high mortality rate. Histologically, the viral lesions consist of characteristic inclusions, particularly amorphous dense bodies containing occluded particles.
Do rotifers swim?
Rotifers may be free swimming and truly planktonic, others move by inchworming along the substrate whilst some are sessile, living inside tubes or gelatinous holdfasts. About 25 species are colonial, either sessile or planktonic.
Do rotifers have eyes?
Every rotifer has eyes and ocelli. Most frequently, there is one eye on the brain and two anterior ocelli in the rotatory apparatus.
What makes bdelloid rotifers so unique?
Bdelloid rotifers are one of the strangest of all animals. Uniquely, these small, freshwater invertebrates reproduce entirely asexually and have avoided sex for some 80 million years. At any point of their life cycle, they can be completely dried out and live happily in a dormant state before being rehydrated again.
Can rotifers harm humans?
How many species of rotifer are there in the world?
Rotifer, also called wheel animalcule, any of the approximately 2,000 species of microscopic, aquatic invertebrates that constitute the phylum Rotifera.
What’s the alternative name for the word rotifer?
Alternative Titles: Rotifera, wheel animalcule. Rotifer, also called wheel animalcule, any of the approximately 2,000 species of microscopic, aquatic invertebrates that constitute the phylum Rotifera.
Why is a rotifer called a wheel animalcule?
Rotifer, also called wheel animalcule, 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.
What kind of body does a rotifer have?
Most are free-living; some are parasitic. Most live as individuals, but a few species form colonies. Most rotifers are only 0.1 to 0.5 mm (0.004 to 0.02 inch) long. The body may be spherical, flattened, bag-like, or wormlike. The body wall consists of a thin cuticle.

What kind of water does a rotifer live in?
Rotifers are so named because the circular arrangement of moving cilia (tiny hairlike structures) at the front end resembles a rotating wheel. Although common in freshwater on all continents, some species occur in salt water or brackish water, whereas others live in damp moss or lichens.
