Information: |
Rayed dorsal fin inserted
above half of pectoral fin, spine smooth, shorter than head
length and not reaching adipose fin origin when depressed. Adipose
dorsal fin short, seperated from the caudal base. Pectoral fin
not reaching pelvic fin, spine with 18 to 24 antorse teeth along
inner margin and 15 to 20 retorse teeth along outer one. Pelvic
fin not reaching anal fin. Anal fin when laid flat reaching
caudal base. Caudal fin forked, lobes equal. Least depth of
caudal peduncle 1.0 to 1.5 in its length. Lateral line complete,
straight. Colour: Uniformly ash-gray. Live
specimens slightly golden coloured, bright yellow and body with
fin tips tinged black. Eyes bright violet and barbles black.
Remarks: Differs from other congeners
in its large head with mucous secretion and dentition. A common
species during winter months, kept alive by its own copious
mucous secretion. Fishermen keep them in earthern pots. The
dermal papillae and moisture keep them alive for several hours.
The thick skin on the dorsal surface of head between eyes and
occipital process is covered with a heavy layer of muscle which
secrets the mucous. Rita species are found in
large rivers throughout the Indian subcontinent and Myanmar.
