Description and Significance

Appearance:
Bdelloid rotifers are microscopic organisms that are usually between 150 to 750 µm long. Their bodies are made up of three main regions: head, trunk, and foot. Usually, bdelloids have a well developed corona that is divided into two parts on a retractable head. Bdelloid rotifers can only be identified by eye while they are alive in order to see how they feed and crawl, which are their defining characteristics for classification. Through a weak hand lens, bdelloid rotifers appear as tiny white dots.

Habitat:

Significance:

describe the appearance, habitat, etc. of the organism, and why you think it is important.

Genome Structure

Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence?


Cell Structure, Metabolism and Life Cycle

Interesting features of cell structure; how it gains energy; what important molecules it produces.


Ecology and Pathogenesis

Habitat; symbiosis; biogeochemical significance; contributions to environment.
If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
