Dorsal spines (total): 1; Dorsal
soft rays (total): 6 - 6; Anal soft rays: 12 - 14. Body moderately
elongate. A deep head, its height more than 66% of the head
length. An obtusely pointed snout, slightly rounded. Eye-diameter
longer than the length of the nasal barbel. Nasal barbel short,
hardly reaching the anterior edge of the orbit; maxillary barbel
moderate reaching the tip of the humeral spine; outer mandibulary
barbel moderate, up to the posterior end of the operculum; inner
mandibulary barbel reaching the end of the orbit; the two pairs
of slender mandibulary barbels are distantly set and in between
small papillae are found. A low number, 13-14, of slender gill
rakers. Humeral spine well developed, but not reaching beyond
the level of the dorsal spin. Dorsal spine short, strongly serrated
on the posterior side; pectoral spine well developed, strongly
serrated on the inner side. Dorsal fin short, much shorter than
the head length; pectoral fin short, not reaching the base of
the ventral fin; anal fin moderate, its base longer than or
equal to the base of the adipose fin. Adipose fin small, the
length of its base shorter than the length of the base of the
dorsal fin). Colour: Preserved specimens are
dark brown above the lateral line and lighter beneath; sometimes
there is a black band behind the operculum. The dorsal and caudal
fin may show a tiny black margin. This is stated as a smalll
Chrysichthys species which may be is imported
as C.
longipinnis or
C. sp. furcatus in the trade. The first three
specimens in the photo's are just under 2ins (5cm) in size and
the last three are 12 months later. |
