Bronze and black pigment has filled the previously-translucent dorsal and anal fins, as well as half of the caudal fin
Morphological analysis included comparison of the external colouration (Gambetta zones, spots on the caudal fin
base and dorsal blotches), shape and colouration of the head, scale coverage, structure of scales, length of barbels (mandibular, maxillary and rostral) and length of urogenital papilla between females and males of each species.
Thus, the morphometric and histological data reveal that the regeneration of caudal fins
occurred normally in the control group, whereas the process was delayed in the group treated with dexamethasone.
The fins are olive in colour and the dorsal and caudal fins
have a yellow to orange (sometimes whitish) margin.
Unpaired fins hyaline with light brown and spots bars on the basal portion of the dorsal, anal and caudal fins
Abdomen and caudal fins
were badly infected by Aspergillus spp.
scales at base of caudal fin
elongate and with posterior margin lobed, Fig.
Despite its caudal position, the fish caudal fin
is not an analogous tissue to the tails of terrestrial vertebrates but is thought to be a derivative of the somatic and/or lateral plate mesoderm that originates from the ventral side of the posterior trunk (see Fig.
The cysts were found in muscles, gills and caudal fins
of fish hosts which were fed to pigeons, chickens and ducks.
6 in SL; colour light grey with a midlateral blackish line from behind eye to posterior caudal peduncle; first dorsal spine blackish, a yellow line at base of fin; two rows of yellow spots in second dorsal and caudal fins
, and one row in anal fin; a yellow line in middle of caudal fin
5 cm wide); paired pectoral fins present; single dorsal, anal, and caudal fins
present; two long rows of scales of leading edges of fins in UALVP 43150 possibly belonging to ventral (= pelvic?
The rear edges of the dorsal and caudal fins
are darker, and there may be a black spot near the pectoral fin.
corneta is orange or brown with pink dorsal, anal, and caudal fins
(Robertson and Allen 2015) and F.
There are four or five striations on the dorsal and caudal fins
Colour in alcohol: males pale yellow, bands mentioned above on dorsal, anal and caudal fins
dusky to black, paired fins translucent.
