Fontinalis antipyretica

Commonly called the sharp-leaved fontinale, is a species of aquatic moss belonging to the Fontinalaceae family. This plant is widely distributed in temperate and cold regions around the world, and it is often found in rivers, streams, lakes, and other aquatic habitats.

Distinctive features of Fontinalis antipyretica include its flexible stems that form floating mats on the water surface. The leaves of this moss are closely arranged along the stems, usually in an opposite or whorled fashion. The leaves are long, narrow and pointed, giving the plant an elegant, prickly appearance.

This aquatic moss has a great capacity to adapt to different levels of light and substrate conditions. It is often used in freshwater aquariums due to its ability to absorb nutrients from the water, helping to maintain balanced water quality. In addition to its use in aquariums, Fontinalis antipyretica also plays an important ecological role as a component of aquatic ecosystems, providing shelter and a food source for various aquatic organisms.
