What are the characteristics of 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 functions do the rotifer’s cilia perform?
The anterior end or corona of rotifers is ciliated; in some species the periphery is ciliated as well. The movement of the cilia functions both in locomotion, especially among planktonic forms, and in movement of food particles toward the mouth.
What is the taxonomy of Rotifera?
Taxonomy. Rotifers belong to the superphylum Platyzoa. Rotifers are typically divided into three classes—Monogononta, Bdelloidea, and Seisonidea—although Acanthocephala (spiny-headed worms, thorny-headed worms) are sometimes placed with Rotifera as well.

What is the function of the Mastax found in rotifers?
The primary function of the mastax is to grind food particles, however, common adaptations are for grasping or sucking in complete food particles or the contents of large prey.
What is the role of rotifers in aquaculture?
Rotifers are regarded as living food capsules for transferring nutrients to fish larvae. These nutrients include highly unsaturated fatty acids (mainly 20: 5 n−3 and 22: 6 n−3) essential for survival of marine fish larvae. In addition, rotifers treated with antibiotics may promote higher survival rates.
What is the importance of rotifers in aquaculture?
Rotifers are popularly called as wheel animalcules. They are an important group of live food organisms for use in aqua hatcheries. Brachionus, which is the most known form of all rotifers, serve as an ideal starter diet for early larval stages of many fish and prawn species in marine as well as freshwater.
What is the meaning of Rotifera?
Definition of rotifer : any of a class (Rotifera of the phylum Aschelminthes) of minute usually microscopic but many-celled chiefly freshwater aquatic invertebrates having the anterior end modified into a retractile disk bearing circles of strong cilia that often give the appearance of rapidly revolving wheels.
What is the environmental or ecological importance of rotifers in the ecosystem?
Rotifers colonize habitats quickly and convert primary production (algae and cyanobacteria) in a usable form for secondary consumers, making energy available for the next trophic levels. In interstitial water from swampy soils, they contribute to nutrient recycling [4].
What is Ploima in botany?
Ploima: includes the majority of rotifers, benthic fresh-water or pelagic fresh-water. SO. Flosculariacea: sessile and fresh-water free-swimming rotifers.
What are the different types of rotifers?
nuclear number is constant at about 900-1000 nuclei per rotifer. O. Seisonacea: marine, epizoic rotifers. O. Bdelloidea: the fresh-water bdellid rotifers, typically benthic. SO. Ploima: includes the majority of rotifers, benthic fresh-water or pelagic fresh-water. SO. Flosculariacea: sessile and fresh-water free-swimming rotifers. SO.
What are pelagic and limnetic rotifers?
Pelagic and limnetic rotifers are estimated at ~1000/liter in lakes and large ponds. They swim continuously, by means of their locomotory corona, and capture prey with the corona and/or with mastax protrusion. These rotifers are transparent and sacciform or stout with the foot reduced, lost or displaced ventrally.
What are some examples of rotifers that swim?
Philodina roseola swimming – note the two spurs at the posterior end – it is one of the most common species of rotifers. Bdelloidea, Philodinidae. The corona of cilia can provide locomotion or the rotifer can move by creeping like an inch worm.
