Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Dorsal view shows the male with larger pectoral fins and the female with fuller abdomen (Ref. 44091). Body is mottled with darker greenish-gray to dark brown markings, against a yellow-brown to brown color; conspicuous adipose crests along the ventral and dorsal mid-lines of the caudal peduncle; 10 barbels; suborbital spine hidden in the skin (Ref. 27732).
Body shape (shape guide): elongated.
Facultative air-breathing (Ref. 126274); Adults occur in rivers, lakes and ponds. Also in swamps and ricefields (Ref. 27732, 119549). They prefer muddy bottoms, where they hide in the muck and leaf litter with only their heads sticking outi, They can also be found under mats of honohono (Commelina diffusa and California grass (Brachiara nuatica). They feed on worms, small crustaceans, insects, insect larvae, and other small aquatic organisms (Ref. 44091).
Male wraps his body around the female and stimulates her to release a cloud of eggs, which the male simultaneously fertilizes (Ref. 44091).
