This species is characterized by the following: usual number of vertebrae, precaudal 15 (14), caudal 56-57 (54-58), total 71-72 (69-72); fin rays, dorsal 127-130 (125-133), anal 106-108 (104-112) pectoral 20-21 (22); pyloric caeca usually 3 (1-4), most often with 2 in one tier and 1 in second, when 4, they are 3+1; first gill arch with rudimentary rakers 2 on the upper arm, 4 (rarely 5) developed rakers on the lower limb, usually 2 (1-3) rudimentary rakers anteriorly on the first arch; total rakers usually 8-9; dorsal-fin origin between neural spines 2-3 (18 specimens) or 3-4 (11 specimens), in most instances is almost directly over neural spine 3 (Ref. 91765). |
