What does the word rotifer mean?

: 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 are the organs of a rotifer?

The body form of rotifers consists of a head (which contains the corona), a trunk (which contains the organs), and the foot. Rotifers are typically free-swimming and truly planktonic organisms, but the toes or extensions of the foot can secrete a sticky material forming a holdfast to help them adhere to surfaces.

How does a tiny animal called a rotifer travel through the water?

The rotifers make up a phylum of microscopic, and near-microscopic pseudocoelomate animals. 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. …

What does rotifer mean in Latin?

ro·ti·fer. (rō′tə-fər) Any of various microscopic aquatic invertebrate animals of the phylum Rotifera, having at the head end a wheellike ring of cilia used for feeding and locomotion. [From New Latin Rotifera, phylum name : Latin rota, wheel; see rota + Latin -fer, -fer.]

Do rotifers have DNA?

New DNA for rotifers Some genes were typical of fungi or bacteria, and endowed the rotifer with handy new properties such as breaking down toxins or using new foodstuffs. This “horizontal transfer” between rotifers and other organisms is ancient and ongoing. Foreign DNA is spread all over the rotifer genome.

What kind of body does a rotifer have?

The body form of rotifers consists of a head (which contains the corona), a trunk (which contains the organs), and the foot. Rotifers are typically free-swimming and truly planktonic organisms, but the toes or extensions of the foot can secrete a sticky material forming a holdfast to help them adhere to surfaces.

How is the infusorian similar to a higher animal?

This has been shown by the careful experiments of Maupas, who had observed 215 generations of an infusorian without sexual union. The Infusorian can be called potentially immortal, because of this method of reproduction. Now the single-celled Infusorian is in many respects comparable with the single-celled germ of the higher animals.

How did the phylum Rotifera get its name?

Phylum Rotifera. The rotifers are a microscopic (about 100 µm to 30 mm) group of mostly aquatic organisms that get their name from the corona, a rotating, wheel-like structure that is covered with cilia at their anterior end (Figure 1).

Where is the brain located in a rotifer?

Rotifers have a small brain, located just above the mastax, from which a number of nerves extend throughout the body. The number of nerves varies among species, although the nervous system usually has a simple layout. Close to the brain lies a retrocerebral organ, consisting of two glands either side of a medial sac.
