Of, relating to, or living in rivers; produced by or found in river environments.
From Latin fluviatilis (of or relating to rivers, from fluvius river). This Latinate form is more formal than its English equivalent fluvial, carrying the weight of scientific nomenclature.
Fluviatile organisms have adapted to some of the most turbulent and changeable environments on Earth—river creatures are constantly battling currents, yet they thrive, making them remarkably tough.
