Relevant Information: |
Dorsal spines (total): 0; Dorsal
soft rays (total): 72-88; Anal soft rays: 56 - 71; Vertebrae:
55 - 60. Head rather pointed in dorsal outline; snout slightly
rounded; eyes located more dorsally. Frontal fontanelle short
and squat (`sole-shaped'); occipital fontanelle small and
oval-shaped. The `dermosphenotic' and supraorbital bones become
sutured in larger specimens (above 65 mm SL). Tooth plates
relatively small. Pectoral spine robust and slightly curved.
Number of gill rakers varies with SL. Suprabranchial organ
well developed, nearly filling the cavity. Openings of the
lateral branches of the lateral line irregularly placed. Found
in lakes, rivers and floodplains (during breeding season).
Stomach contents consisted of sand, plants, larvae of Ephemeroptera,
Trichoptera and Chironomidae, remains of insects and fish
scales. Juvenile specimens were found in isolated pools in
the forest which might indicate that reproduction takes place
during the rainy season. |
