The gut of the pterobranch hemichordate Cephalodiscus nigrescens contains plankton of sizes from less than 1 μm to over 100 μm in diameter. Some of the smaller plankton are clumped together in spherical bolus that is mucus‐bound. Most plankton types known from the habitat are respresnted amongst the gut contents.
