Definition of Term

pharyngeal tooth count
(english) Pharyngeal tooth counts (of Cyprinidae) are presented in a formula from the outer to the inner rows of the left arch, then the inner to the outer rows of the right arch, e.g. 2,5-4,2 means 2 teeth in the outer and 5 teeth in the inner row of the left arch and 4 teeth in the inner and 2 teeth in the outer row of the right arch. If variation in the outer row occurs it may be written as 1 or 2, 5-4, 2 or 1; or as 2,5-4,2 or 1,5-4,1. Periods and colons are sometimes used to separate the inner and outer rows; 1.4-4.1; 1:4-4:1. The third row, if present, is placed at the beginning and end of the formula 1,3,4-4,2,1. There may be no teeth in outer rows, e.g. 5-4. As there is only one row on pharyngeal arches of Catostomidae usually the count of only the left arch is given.
