Cliff ferns belong to a family of ferns known for their delicate, lacy fronds and typically clustered leaflets. These ferns thrive in moist, shaded environments, often found carpeting forest floors or nestled in rocky crevices, leveraging these habitats to maintain the humidity necessary for their spore-driven reproduction. Their adaptive nature allows them to flourish under a forest canopy, utilizing the filtered light, which enhances their intricate leaf structures.
