Glacialis

Glacialis is a Latin adjective meaning "of ice" or "icy," derived from glacies, ice. In scientific naming, glacialis is commonly used as a species epithet (the second part of a binomial name) to indicate an association with cold or glacial habitats, or a resemblance to ice. As with other Latin adjectives, glacialis must agree in gender with the genus name, so its ending can vary to fit masculine, feminine, or neuter forms in different scientific names.

The epithet glacialis is widely applied across many taxonomic groups, including plants, fungi, and animals. It does not denote a single taxon or lineage. Instead, it serves as a descriptive descriptor that taxonomists attach to new or reclassified species when the type locality, range, or appearance connects the organism to icy environments or ice-like characteristics.

In practice, a species bearing the epithet glacialis is typically associated with high latitudes, alpine or glacial regions, or features that evoke ice in appearance. The use of glacialis helps convey ecological or morphological information within the formal Latin name while remaining distinct from the broad range of other epithets used in taxonomy.
