Comparative scale morphology and squamation
patterns in triplefins (Pisces: Teleostei: Perciformes: Tripterygiidae).
nomenclature follows that described by Hoedeman (1958), and the cephalic neuromast series are described according to Costa (2006).
Scale morphology and squamation
patterns in cichlids (Teleostei, Perciformes): Acomparative study.
1 n order to determine die cellular origin of these hyperplastic lesions and the possible presence of squamation
, the tissue sections were imnumohisrochemically evaluated using several cytokeratin and epithelial cell markers in SHHF rats.
Comparing with adults plaque-type psoriasis lesions in childhood are more itchy, with finer, softer and less squamation
The two types of pen shell--scaly type and smooth type--are defined by the presence or absence of squamation
of the shell surface (Torigoe 1985).
A combination of morphological characters, pigmentation, preopercular spine pattern, meristic counts, and squamation
in later developmental stages is essential to identify Icelinus to the species level.
beniensis, from the rio Madeira drainage; Owiyeye is diagnosed by the absence of dermosphenotic, a derived pattern of frontal squamation
, and a colour pattern of the mandibular region, and includes species from the Amazonas and Orinoco river basins; Melanorivulus is diagnosed by an apomorphic morphology of preopercle, and derived colour patterns of male postorbital region and female unpaired fins, and includes species from southern Amazonian tributaries, Parana-Paraguay river system, and Parnaiba and Sao Francisco river basins.
of thelodont type; contiguous scales longitudinally strongly stretched, the width : length ratio up to 1 : 11.
Although he could find no differences in color pattern or squamation
between it and the adjacent peninsular populations of C.
Enlarged post-occipital squamation
is relatively rare in the estuarine crocodile.
Terminology for frontal squamation
follows Hoedeman (1958); the E- scale was determined as that scale adjacent to the anteriormost neuromast of the posterior section of the supraorbital series.
