Blekeagentia

Blekeagentia is a fictional genus used in introductory biology to illustrate the conventions of taxonomic classification and phylogenetic reasoning. It is presented in educational scenarios as a group of small, planktonic marine protists characterized by a translucent, silica-rich skeleton and a simple, single-celled body plan. In the standard fictional account, the genus comprises four species: Blekeagentia lutea, Blekeagentia obscura, Blekeagentia profunda, and Blekeagentia ventis. These species are described as inhabiting cold, nutrient-rich deep-sea waters and forming short-lived colonies under certain hydrothermal or nutrient-rich plume conditions.

Morphology and physiology: species are typically about 10–40 micrometers in size, have tentacle-like feeding projections, and produce bioluminescent flashes under stress. Ecology: they are filter feeders, contributing to particulate organic matter turnover in their simulated ecosystems. Distribution: shown as cosmopolitan in deep-sea sediments and midwater columns in educational diagrams, with higher reported abundances near polar regions in some exercises.

Taxonomy and naming: Blekeagentia is placed within a hypothetical family Blekeidae and order Blekeamorpha, within a broader protist-like supergroup used for teaching.
