In the lancelet Hatschek's pit, also called Hatschek’s nephridium, is an unpaired kidney whose duct opens into the anterior pharynx. It can be seen as a deep ciliated fossa on the dorsal midline of the buccal cavity (mouth). Among other things, it secrets mucus which entraps food particles from the water.
