Information: |
The combination of the
absence of a spinelet associated with the dorsal fin, the absence
of spines on the dorsal and pectoral fins, and the possession of
a single row of teeth on the vomer distinguishes Cetopsis
from the other genera in the Cetopsinae. This species
can be distinguished from all of its congeners by the combination
of the presence of an eye, the conical teeth on the vomer and the
dentary, the rounded posterior nares that is distinctly separated
from the contralateral nares by a distance greater than the width
of the posterior nares, the dark humeral spot, the pattern of a
darkly pigmented pectoral and pelvic fins other than for thin, clear
margins, and the possession of 23 to 25 total anal-fin rays.
