Morphological features, including the development of the opercular complex and head spination, the sequence of development of meristic
characters, and the position and relative size of the melanophores in preflexion, flexion, and postflexion larvae, allowed reconstruction of a developmental series and identification of the remaining individuals studied as A.
Our purpose was to provide evidence on the specific identity of the unusual lizard and document its existence with photographs in addition to descriptions of color pattern, scutellation, meristic
, and body size characters.
The three species share certain morphological features such as general body coloration, approximate maximum size and meristic
information is given as the range followed by the mean and number of specimens examined.
By the time Gonads were removed, they were inspected for metric and meristic
(2012) conducted a study on the variation in phenotype based on morphometric character indices and meristic
counts among different wild and cultured Nile tilapia (Oreochromis niloticus).
babcocki (Thompson, 1915) until Rosenblatt and Chen (1972) clarified the distinction of these species and pointed out a number of meristic
and morphological characteristics that definitively separate these two species.
Fish collected from the beach-seine were numbered and samples of whole fish were used for morphometric and meristic
analysis to confirm the taxonomical identification of the species (MENEZES, 1983; SOARES, 1988).
clara in the upper Ohio River (Kanawha River basin) of West Virginia, reports meristic
characters of this population (based on 16 specimens), compares data with those of Williams (1975) and Starnes et al.
These authors briefly discussed their meristic
and morphometric data in relation to values from Venezuelan populations given by Gilbert and Caldwell (1967) and attributed the differences found to intra-specific variation.
Multivariate statistical techniques were used to compare the morphometric and meristic
characters currently used to differentiate syngnathids.
Both species share similar meristic
features and morphometric proportions, which is typical for the various members of the genus, which are best separated on the basis of colour pattern differences in adult males.
