Two regions of ciliated epithelium are described in the digestive tract of the halibut larva. The anterior region, present by 5 days post‐hatch and still present at 25 days post‐hatch, probably moves water through the branchial openings into the oesophagus and on to the midgut until the mouth forms at about 29 days post‐hatch. A ciliated region was present also in the occluded posterior hindgut, which joins the excretory duct to form a common duct to the exterior. This posterior ciliated region may help to circulate water in the mid‐ and hindgut until the anus opens directly to the exterior, at about 25 days post‐hatch.
