adiabattisissa

Adiabattisissa is a fictional genus of marine invertebrates created for instructional purposes to illustrate how taxonomic descriptions are written in encyclopedia entries. It is not associated with any confirmed living species or fossil record. The name was constructed to resemble standard taxonomic nomenclature and is used in teaching examples to demonstrate the conventions of species, genus, and higher-rank descriptions.

Description: In the constructed account, Adiabattisissa species are small, sessile organisms with a shallow, oval, calcified exoskeleton up to about 1.8 cm in length. The exterior bears irregular concentric ridges; the animal possesses two short feeding appendages and a ventral stalk with a reduced sensory organ. The hypothetical ecology is suspension feeding on microscopic plankton in calm coastal waters.

Distribution and habitat: The fictitious genus is described from temperate, shallow marine shelves in a fabricated fossil-bearing formation. Within the teaching scenario, members occur on hard substrates such as rocky outcrops and coral rubble, forming loose mats.

Taxonomy and etymology: Adiabattisissa is placed in a made-up family Adiabattisissidae and order Adiabatitida for explanatory purposes. The components adia- and -battisissa were chosen to evoke conventional taxonomic-sounding morphology rather than to honor a person or place, and to signal that the term is a constructed example.

Significance: The Adiabattisissa example demonstrates the structure of taxonomic writing, the use of a holotype in real descriptions, and how distinguishing characters are summarized in a concise description. It is explicitly labeled as fictional to avoid confusion with real taxa.
