Fish are cold-blooded vertebrates, whose body movements and balance mainly using fins, breathing through gills, living in an aquatic environment. Most vertebrates the world fish covering 48.1%, mammals (10.8%), reptiles (14.4%), amphibians (6.0%), birds (20.7%). One of consumed North Sulawesi is scad mackerel locally called malalugis. This research focused on meristic morphometric characteristi...

After around a hundred years of being without any record of occurrence of Paracobitis rhadinaea, a species of Nemacheiline loach, in Sistan basin, southeast of Iran, the year 2012 was the turning point of wild life in this area. Twenty-five specimens were caught from Chahnimeh Reservoir, a water body adjacent to the Hamoun Wetland in Sistan basin. Morphometric and meristic characteristics were ...

The first two specimens of Regalecus glesne Ascanius, 1788, collected in the Argentine Sea, at Playa Unión beach, 43o 18' S, 65o 02' W are reported. Body measurements, meristic characters and morphological data are given. The most important differences with two other regalecid species, R. russelii Cuvier and R. kinoi Castro-Aguirre et al. 1991, from the Pacific coasts of Mexico, are considered....

the present study reports range extansion of moenkhausia oligolepis to the pindaré river drainage, of the mearim river basin, and itapecuru river basin, maranhão state, northeastern brazil. this species was previously known only from venezuela, guianas, and the amazon river basins. in addition, we present some meristic and morphometric data of the specimens herein examined and discuss on its di...

random regression models (rrm) have become common for the analysis of longitudinal data or repeated records on individual over time. the goal of this paper was to explore the use of random regression models with orthogonal / legendre polynomials (rrl) to analyze new repeated measures called clutch size (cs) as a meristic trait for iranian native fowl. legendre polynomial functions of increasing...

A new record of the one stick sting fish Minous coccineus (Scorpaeniformes: Synanceiidae) was documented based on morphological traits and DNA barcoding. The species acquired by Department Fisheries during yearly survey “RV Meen Sandhani” from maritime area Bangladesh's continental shelf in Bay Bengal 2018 to 2019. first Bangladeshi marine waters has been verified barcoding morpho-meristic anal...

Based on 270 specimens from 7 populations of Lacerta alpina, L. caucasica, L. daghestanica and L. praticola, morphological relationships between the four species were studied for 7 meristic characters and 5 morphometric characters, using canonical variate analysis. In both scalation and morphometry, the contours and centroids of the studied populations form a trend: L. praticola – L. caucasica ...

Most members of the genus Calaxias are small to mediumsized, fast-swimming, mid-water fishes that can be either lacustrine or diadromous (Whitley 1935). However, one species, Calaxias cleaveri Scott 1934, differs so markedly from typical Tasmanian members of the genus that at one stage it was referred to tpe genus Saxilaga by Scott (1936). Meristic and morphometric comparison of the mainland Ta...
