Morphology | Morphometrics
Vertebrae: 36 - 37. Differs from its congeners, Danionella translucida and Danionella mirifica, in having the following characters: a single bone in the upper jaw (versus two); a single row of 6-13 odontoid processes in males on the dorsal surface of the dentary and on the ventral surface of the upper jaw, the anteriormost processes of which are large and canine-like
(versus absence of processes); absence of maxillary-mandibular cartilage (versus presence); the possession of 7C8, 8C7 or 8C8 principal caudal fin rays (versus 9C9), dorsal procurrent rays 3-4 (versus 5-6) and ventral procurrent rays 2-3 (versus 4-6) (Ref. 81221).
