Information: |
Dorsal soft rays (total):
6 - 6; Anal soft rays: 23 - 24; Vertebrae: 39 - 40. The combination
of the presence of a dorsal fin with an ossified spinelet and the
presence of pectoral and dorsal-fin spines distinguishes the species
of Cetopsidium from all other genera in the Cetopsinae.
The possession of a lateral line extending to over the posterior
portion of the base of the anal fin but falling short of the caudal
peduncle is also unique to Cetopsidium within the Cetopsinae.
This species differs from all other species of Cetopsidium
in the length of the pelvic fin (tip of fin reaching posteriorly
to the anal-fin origin versus only reaching or falling short of
the vent, respectively). |
