Remove ads
In the lancelet, Hatschek's pit, not to be confused with Hatschek's nephridium, is a deep ciliated fossa on the dorsal midline of the buccal cavity (the region of the gut behind the mouth).[1] Among other things, it secretes mucus which entraps food particles from the water. It is named after Berthold Hatschek, an Austrian zoologist who worked on the lancelet.[2]
