Etymology: hypselurus: From the Greek hypselos for high and oura for tail, in reference to the relatively tall neural spines of the caudal vertebrae (Ref. 45707).
Eponymy: Dr Heinrich Breitenstein (1848–1930) was a German physician who served with the Dutch East Indies army for 21 years. [...] (Ref. 128868), visit book page.

Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 1; Raggi dorsali molli (totale) : 5; Spine anali: 0; Raggi anali molli: 10; Vertebre: 42. Differentiated by its relatively tall neural spines in the caudal vertebrae, shorter caudal peduncle (26.0% SL versus 30.7-36.8), longer snout (35.5% HL versus 27.2-34.1), more wide-set eyes (interorbital distance 30.9% HL versus 27.2-34.1), fewer vertebrae (42 versus 44-45), and smooth (versus serrated) dorsal spine (Ref. 45707).
Body shape (shape guide): elongated.
