vermiculus

Vermiculus is a Latin-derived term meaning "little worm" or "worm-like." It functions as a descriptive epithet in scientific naming and as a root in terms describing textures, patterns, or forms that resemble worms. It is not a standalone taxonomic group, but rather a Latin adjective used across disciplines to convey a worm-like appearance or habit.

In taxonomy, vermiculus appears as a specific or subspecific epithet in various animal and plant names. When used in this way, it signals that the organism or a feature of it bears worm-shaped characteristics or has a worm-like pattern. The epithet is descriptive rather than implying a distinct lineage or clade.

In mineralogy and geology, the root informs the name vermiculite, a hydrous phyllosilicate mineral with a flaky, expandable structure. The name evokes a worm-like, serpentine texture seen in some forms. The term vermiculate is also employed to describe worm-like markings on rocks, fossils, or plant tissues, reflecting a similar visual or structural motif.

Across botany, paleontology, and related fields, vermiculus and its derivatives serve primarily as descriptive language rooted in Latin. They help convey resemblance to worms in morphology, patterning, or microstructure. The usage remains historical and descriptive, rather than carrying taxonomic authority on its own.
