Definition
Heterotrichales are an order of filamentous algae within the Xanthophyceae (yellow-green algae). These algae are characterized by their heterotrichous growth habit, meaning they have both prostrate (horizontal) and erect (vertical) filaments. They are typically found in freshwater habitats. Think of them as the branching artists of freshwater ecosystems ๐ณ, creating intricate patterns. They reproduce both sexually and asexually.
