Kort beskrivning
Bestämningsnycklar | Morfologi | Morfometri
Ryggkotor: 26. This species is distinguished from its congeners except H. elongatum, by the presence of a patch of odontodes on the anterolateral surface of the cleithrum at the opening to the branchial chamber. It is distinguished from H. elongatum by having a shorter caudal peduncle, with caudal-peduncle length 26.0-36.0 (32.0) (vs. 32.3-36.3 (34.4); t-test, p < 0.001); with a deeper, more robust caudal peduncle, caudal-peduncle depth 8.8-11.0 (10.1) (vs. 7.9-8.8 (8.4); t-test, p < 0.001); by the round to slightly acute snout (vs. snout appearing pointed due to slight lateral inflexion between rostral plate and first infraorbital); by fewer plates along medial series 21-22 (22) (vs. 23); and by having light brown caudal-fin lobes (vs. dark lobes) (Ref. 84367).
Body shape (shape guide): elongated.
Facultative air-breathing in the genus (Ref. 126274)
