Etymology: Glyptothorax: Greek, glyptes = carver + Greek, thorax = breast (Ref. 45335); exodon: From the Greek exo, meaning out, and odontos (tooth), in reference to the exposed premaxillary teeth.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Tropical

Morphology | Morphometrics
soft rays: 12 - 13;
Vertebrae: 35 - 37. Distinguished from Sundaic congeners except Glyptothorax platypogonides and G. siamensis in possessing a slender body (13.8-15.8% SL). Differs from G. platypogonides in having a deeper caudal peduncle (6.8-7.3% SL vs. 5.7-6.7) and more exposed premaxillary teeth when the mouth is closed and from G. siamensis in having a larger eye (10.4-13.2% HL vs. 7.5-9.1) and a mottled color pattern lacking distinct pale stripes (vs. a uniform dark brown with distinct pale midlateral and mid-dorsal stripes) (Ref. 56938).
Inhabits swift, clear streams with a substrate consisting of gravel, cobble or large rocks (Ref. 2091).
