Class
Bdelloidea are a class of rotifers. There are over 450 species of bdelloid rotifers distinguished by their morphology. This includes species such as Adineta ricciae, Rotaria rotatoria, and Philodina acuticornis. Bdelloidea's species concept is based on molecular and morphological data due to their asexual nature.
Description and Significance
Appearance:
Bdelloid rotifers are microscopic worm-like organisms that are usually between 150 to 750 µm long. Their bodies are made up of three main regions: head, trunk, and foot. 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:
Bdelloidea can be found in fresh and brackish water all over the world. They can also be found in moss, lichen, and soil while also being able to survive dry, harsh environments through desiccation-induced dormancy, also known as anhydrobiosis. Bdelloid rotifers are considered to be cosmopolitan.
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.
