Urechis unicinctus

Urechis unicinctus, known as the fat innkeeper worm or penis fish,[3][4] is a species of marine spoon worm in East Asia. It is also known as garloid colloquially. It is found in Bohai Gulf of China and off the Korean and Hokkaido coasts.[4] It is not to be confused with a closely related species, Urechis caupo, which occurs on the western coast of North America and shares common names.[5] The body is about 10–30 centimetres (3.9–11.8 in) long, cylindrical in shape and yellowish-brown in color. On the surface of the body there are many small papillae.
