True to its name, the worm-shaped marine invertebrate has 3 parts–an acorn-shaped proboscis, a short fleshy collar and a long trunk. They live in U-shaped sand and mud burrows of ocean floor. They feed on bacteria, diatoms and microalgae by ingesting the sand stuck to them (deposit feeding) and secrete coils of digested sediments called cast. They also do this with water through suspension feeding.
