Are rotifers a species?
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 are examples of rotifers?

Rotifers/Scientific names
What family are rotifers?
Seisonidae
Two classes of rotifers are recognized: class Pararotatoria, comprising a single small family Seisonidae; and class Eurotatoria, containing subclasses Bdelloidea and Monogononta (Segers, 2002; Wallace et al., 2006). Seisonids are exclusively marine and obligatorily sexual.
Is a Rotifera primary consumer?
This level includes both herbivores and carnivores: nematodes, protozoa, rotifers, soil flatworms, springtails, some types of mites, and feather-winged beetles.
What are the characteristics of phylum Rotifera?
Classification of Phylum Rotifera:
- Elongated body with reduced corona.
- Lateral antennae and toes absent.
- Males fully developed and with little sexual dimorphism.
- Gonads paired in both sexes. ADVERTISEMENTS:
- Ovaries without vitellaria.
- Epizoic marine rotifers.
How many species of rotifers are there?
2200 species
About 2200 species of rotifers have been described. Their taxonomy is currently in a state of flux. One treatment places them in the phylum Rotifera, with three classes: Seisonidea, Bdelloidea and Monogononta.
What are the characteristics of the phylum Rotifera?
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.
What are the characteristics of phylum rotifera?
Which structure is common in rotifers?
Is a Rotifera primary or secondary consumer?
The diet of rotifers consists of matter small enough to fit through their tiny mouths during filter feeding. They are primarily omnivorous primary consumers of small microorganisms and suspended organic matter, but some species have been known to be cannibalistic.
