Underwater caves – hunting for new forms of life

Cave-inhabiting animals are often categorized as troglobites (cave-limited species), troglophiles (species that can live their entire lives in caves, but also occur in other environments), trogloxenes (species that use caves, but cannot complete their life cycle fully in caves) and accidentals (animals not in one of the previous categories). Some scientists use a separate terminology for aquatic forms (e.g., stygobitesstygophiles, and stygoxenes).
