Stylaria

Stylaria is a genus of freshwater annelid worms belonging to the family Naididae. These small oligochaetes are commonly found in a variety of aquatic habitats, including ponds, lakes, and slow-moving streams, often inhabiting soft sediments or decaying organic matter. Members of the Stylaria genus are characterized by their elongated bodies, which can be quite slender, and the presence of a proboscis, a retractable, tubular mouthpart. They typically possess a distinct head end with sensory structures.

Reproduction in Stylaria is primarily asexual, occurring through fragmentation or budding. When a segment of the worm detaches, it can develop into a new, complete individual. Sexual reproduction can also occur, but it is less common. These worms play a role in aquatic ecosystems as detritivores, feeding on decaying organic material and contributing to nutrient cycling. Their presence is often indicative of relatively stable aquatic environments. Several species have been described within the Stylaria genus, each with slight variations in morphology and habitat preference.
