Magnetteina

Magnetteina is a fictional genus of small marine invertebrates created to illustrate how taxonomic entries are written in reference works. In the imagined system, Magnetteina is placed within a concise lineage known as the Magnetteinidae, inhabiting temperate coastal lagoons. The genus name blends the root magnet- with a neutral suffix to evoke magnetic orientation observed in its life history.

Discovery and etymology: Magnetteina was first described in a fictional scientific work by Dr. Irena Mora in 2042. The name is intended to reflect the purported magnetoreceptive abilities of the larvae and the shimmering, metallic appearance of the organism.

Description: Species within Magnetteina are small, typically ranging from 3 to 7 millimeters in length. They possess a compact, domed body with subtle surface sculpturing and a pair of lateral appendages that may resemble gills or paddles. The integument is described as pale with iridescent highlights, and individuals are noted for a faint, bioluminescent glow under certain conditions.

Distribution and ecology: In the fictional account, Magnetteina is endemic to a set of temperate coastal lagoons around a stylized archipelago. They are commonly associated with seagrass beds and feed on microalgae and detrital material. Adults are largely sedentary, while larvae exhibit magnetoreception-driven dispersal that aligns movement with geomagnetic cues.

Life cycle and behavior: Magnetteina is described as reproducing sexually, with external fertilization and a short free-swimming larval stage before metamorphosis into a benthic juvenile.

Note: Magnetteina is a fictional construct used for illustrative purposes. Any resemblance to real taxa is coincidental.
