Its scientific name is Urechis unicinctus. It is a species of marine spoon worm widely referred to as the fat innkeeper worm or the man-hood fish. It is common in Asia, and a delicacy there. It is called pinyin in Chinese, yumushi in Japanese, and gaebul in Korean. It lives in burrows in sand and mud. It gets the name “fat innkeeper worm” because the tunnels it creates often contain other animals. This spoon worm is commonly eaten raw with salt and sesame oil in Korea and in parts of Japan.
