The gills of the lampreys
and higher fishes share a similar arch-like
arrangement with intervening branchial slits for
the water to pass laterally from the buccopharyngeal

hagfish gill does not have recognizable arch-like
structures, and so its pouch gills will be dealt with
separately.The gills of the lampreys
