👉 The term "autopelagic" is commonly used in marine biology to describe a type of polychaete worm that primarily feeds on algae. These worms are known for their ability to grow and colonize large numbers of microalgae, which they feed on. The unique characteristic of autopelagic polychaetes is the ability to obtain their food from other organisms, rather than directly consuming them, which makes them a type of "autopelagic" organism.
