Koi Carp, which originated in Japan, come in more than a dozen varieties and are distinguished by their colouring, patterning, and scalation
. The Kohaku variety is a white-skinned koi, with large red markings on the top.
Finally, the population from "Cordillera de Los Altos" can be differentiated from the other species of this genus by subtle characters of coloration and scalation
. Therefore, applying the general lineage species concept , we recognize the Phyllopezus population from the "Cordillera de Los Altos" as a separate species, described below.

analysis of Pseudonaja textilis (Dumeril and Bibron) in the eastern Riverina region.
The representation of convolutional feature is more discriminative than the fully connected feature , and it is more sensitive to translation, rotation, and scalation
The frontal scalation
patter in some groups of toothcarps (Pisces, Cyprinodontiformes).
The three species are distinguished from each other based on head scalation
, length, and distribution (Cogger 2014).
Differences in pigmentation and scalation
were the bases for these opinions.
Table 1 lists features of scalation
, including the number of ventral, subcaudal, labial and ocular scales, dorsal scale rows and definitions of measuring methods.
Furthermore, it is noteworthy to mention here that Coluber bholanathi and Coluber gracilis (Gunther, 1862), an allopatric congener, both share some scalation
and coloration characters in common, except dorsal scale row count --19:19:12-15 (fide Gupta et al.
REIF, W.E., 1987: Evolution of high swimming velocities in sharks a case of scalation
The head is pointed and dorsal scalation
consists of a mixture of small flat scales and other enlarged keeled and tuberculated forming keels.
Physical patterns of the hybrids show a mix of Chelonia mydas and Eretmochelys imbricata scalation
within one pair of prefrontal scales similar to Chelonia mydas and three post-orbital scales per lateral surface similar to Eretmochelys imbricata (figure 9).
