Rotifers live all over the world.


Most rotifers live in freshwater in sand or mud at the bottom, in plants, or in open water. Several species live in saltwater, usually among plants but sometimes between grains of sand on beaches.


Rotifers eat algae and other protists, bacteria, and even other rotifers. Algae (AL-jee) are plantlike growths that live in water and have no true roots, stems, or leaves. Protists (PROH-tists) are one-celled living things that have a nucleus (NOO-klee-uhs), which is the control center of a cell.

Many species of rotifers are cultured as fish food for aquariums and fish farms. They also can be used in tests for water pollution.

WHAT'S IN A NAME?

The name rotifer comes from the Latin words rota, meaning "wheel," and ferre, meaning "to carry." When these animals are swimming or feeding, the beating of their hairlike fibers gives the illusion that the animal carries two small, rotating wheels.

Rotifers are not considered threatened or endangered.

Rotifers: Rotifera - Behavior And Reproduction

Most rotifers collect food by beating the wheel organ to make a water current. Swimming rotifers move gently through the water in a spiral motion. Crawling rotifers use sticky glands on their foot and head to move much the way inchworms do. Some species of rotifers use only sexual reproduction; some use only asexual reproduction, and others have both a sexual and an asexual phase. Asexual (ay-SEK-…

Physical characteristics: Seison nebaliae rotifers are 0.03 to 0.1 inch (800 to 2,500 micrometers) long. Males and females are the same size. The head is egg shaped and has a long neck made up of parts that can retract like the sections of a telescope. The trunk is oval, and the foot is long and made up of sections. Rather than toes, these rotifers have a sticky disk they use to attach themselves …
