The long, mid-posterior preopercular spine extended beyond the cleithrum
58] Posterior flange of cleithrum
(Costa 1998a) (CI: 1.
A distinctive membranous structure on anterior edge of cleithrum
that appears juxtaposed to first lateral scales, and covered with a great number of highly ramified complex tubules.
1) found a row of foramina near the ventrolateral angle on the inner surface of the right cleithrum
However, the small but robust supracleithrum (which one might expect to be removed with the cleithrum
to which it is articulated) is not particularly under-represented.
Two internal melanophores are present in the posterior head region; one is located in the middle of the cleithrum
near the base of the pectoral bud and the second is located on the base of the brain near the cleithrum
A monogeneric atheriniform family with the parasphenoid concave rather than convex, parasphenoid myodomes present; mesethmoid morphology unique, nasal septum formed by ethmoid and mesethmoid; parietals not contributing to posttemporal fossa; anterior vertebral parapophyses with lateral ridges; interdorsals absent; cleithrum
dorsal enclosure absent; membrane just posterior to genital opening; and pelvic posteromedial process elongate.
long, forming trough along anterior edge of girdle.
In cases where one or more of five skull bones (maxilla, premaxilla, dentary, cleithrum
, opercle) were found intact, and in good overall condition, these bones were collected for the purpose of back-calculating original bluefish size with a series of predictive equations (Wood, 2005).
, present at first feeding as a thin band, thickens with growth.
Tags were placed in the hypaxial musculature (ventral to the cleithrum
at a depth of 0.
The ventral end of the cleithrum
is hyperossified in large C.
