Rotifera Phylum Quiz: Wheel Animals

The corona is found on the anterior part of the body.

Phylum Rotifera is a group of microscopic, multicellular organisms that have a unique characteristic called a cilia crown. Cilia are tiny, hair-like structures that surround the mouth of these organisms and are used for various functions such as locomotion and feeding. The cilia crown is a defining feature of Phylum Rotifera and distinguishes them from other organisms.

Rotifers are microscopic aquatic animals that are commonly found in freshwater environments. They have a preference for living near or on aquatic vegetation, such as algae or submerged plants. This association with aquatic vegetation provides rotifers with a source of food and shelter. The vegetation provides a surface for them to attach to and also serves as a habitat for other small organisms that rotifers can feed on. Therefore, the presence of rotifers is often an indicator of a healthy aquatic ecosystem with abundant vegetation.

Phylum Rotifera refers to a group of organisms that are part of the meiofauna, which includes small animals that live in the spaces between sand grains on beaches. Therefore, the correct answer is meiofauna.

The term "pelagic" refers to organisms that live in open water, such as the open ocean. The term "cyclomorphosis" refers to the ability of certain organisms to exhibit changes in cycles, such as changes in their morphology or behavior in response to environmental conditions. Therefore, the correct answer is "Pelagic, cyclomorphosis" because it accurately describes organisms that live in open water and have the ability to exhibit changes in cycles.

The body of the organism being referred to consists of three parts: the corona, the trunk, and the foot.

Rotifera is a phylum of microscopic, multicellular animals commonly known as rotifers. Philodena is a genus within the phylum Rotifera, making it an example of Rotifera.
