Ivana, some species of freshwater suckers have only one row of teeth. I am
familiar with these as they are often exposed in 'blowouts' of the
Pliocene fossiliferous sands of Idaho where I did my first field
collecting many years ago. Mormon pioneers on 19th-century wagon trains
headed westward saw the pharyngeal arches too and called them 'baby jaws',
believing that they were the remains of ante-deluvian sinners. -- Dr. Deb
