Triportheus magdalenae posee dientes tricuspides y multicuspides que estan asociado a morder o desgarrar (Gatz, 1979).
The teeth possess a multicuspid cladodont crown made up of the main central, intermediate and lateral cusps and numerous intermediate and accessory cusplets.
Depth 2.55-2.90 in SL; scales (8)35, 11 transverse; anal fin iii,17; 5-7 interhaemals; mouth terminal, teeth flat multicuspid (up to 7 cusps only) on both jaws; maxilla very short, with 0-1 teeth; colour-pattern rather variable; usually the anterior part of dorsal fin with a falciform black blotch; a broad caudal spot, covering almost all of the depth of the peduncle, not extending onto the middle caudal fin rays; anal fin lobe never black, only the first ray marked; skin over the interhaemals dark.
Depth 2.95 in SL; scales (9)34, 10-10' transverse; anal fin iii,20; about 9 interhaemals; mouth subin-ferior, teeth flat multicuspid (up to 7-8 cusps) on both jaws; maxilla very short, with 1(?) tooth; fins hyaline; a broad caudal spot, covering the depth of the peduncle, truncate posteriorly, not extending onto the middle caudal fin rays, pointed anteriorly; the photo in situ labelled Station 7 shows a silvery lateral band, without striking colours.
The bicuspid, multicuspid and some small tricuspid teeth have the flattest bases.
However, the variability in the crown structure (number of cusps and angles between the lateral cusps), as well as some variability in the base (position of the basal canal and possibly base curvature), suggest that Karksiodus dentition displayed weakly developed heterodonty in which the bicuspid, tricuspid and multicuspid teeth were located in different positions on the jaws.
