genus appendicularia
Noun: A taxonomic genus within the class Larvacea (or Appendicularia). It comprises small, free-swimming tunicates (sea squirts) that retain their larval, tadpole-like form and tail throughout their life. The genus is the type genus for the class.
The word "genus Appendicularia" is used in scientific, specifically zoological and taxonomic, contexts to classify and refer to this particular group of marine organisms. * The species Appendicularia sicula belongs to genus Appendicularia. * Researchers studied the filter-feeding mechanism of organisms within genus Appendicularia.
- In formal taxonomy, the genus name is italicized: .
- The term can be used to discuss evolutionary biology, as these organisms are considered to be neotenic, meaning they reproduce while retaining larval characteristics.
- Appendicularian (noun/adjective): Refers to any member of the class Larvacea (Appendicularia) or describes something related to them.
- The appendicularian house is a complex mucous structure used for feeding.
- Larvacea: The class name, often used synonymously with Appendicularia.
- (As a group): Larvaceans, appendicularians.
The term specifically denotes the genus rank in biological classification. It should not be confused with the identical name of the class (Appendicularia), though the genus is its namesake. The defining feature is the permanent retention of the notochord and tail in a larval-like body.
