Chondrichthyan egg cases are important elements for species-specific identification and also provide a valuable aid in determining species spatial distribution, as well defining spawning areas. Considering the absence of general key Mediterranean Chondrichthyes, this work aims to fill gap by presenting based on morphological features case. The was developed primarily analysing fresh dissected f...

five metric and 10 meristic characters were studied in 30 specimens of eryx (daudin, 1803) in bahr al-najaf depression, al-najaf province – iraq. according to the results, and considering the principle of priority, we concluded that the populations of e. jaculus (linnaeus, 1758) in the study area should be classified into e. jaculus jaculus (linnaeus, 1758) and e. jaculus familiaris echwald, 18...

forty-nine preserved specimens (31 male and 18 female) of trachylepis aurata transcaucsasica were examined with respect to metric and meristic features and dry skull anatomy to assess sexual dimorphism. thirty-one morphological characters and 36 anatomical characters in dry skulls were examined. subdigital lamellae under the forth toe, neck length, neck length/snout vent length, and six skull c...

abstract lizards have significant roles in life cycle and are related to humans either directly or indirectly. identifying of the fauna of a region is the most necessary and the most significant biological and fundamental research in it. mazandaran province has diverse biological conditions because of its geographical location and special ecological conditions, the proximity of the sea to the m...

Several major systematic papers have recently been published on the perciform fish family Kyphosidae. One is a world revision of the family by Knudsen and Clements (2013), based largely on information summarized from an unpublished molecular phylogenetic analysis, supplemented by meristic and morphometric data. The second, by Sakai and Nakabo (2014), is a review of the genus Kyphosus from the A...

The Stripetail Darter, Etheostoma kennicotti (Putnam), is widely distributed in tributaries of the lower Ohio River, upper Green River system, Clarks throughout Tennessee Laurel and Cumberland system. cumberlandicum Jordan Swain was described 1883 from a population sampled Clear Fork system that drains to Cumberland. A previous morphological analysis led placement E. into synonymy kennicotti. R...

Investigations on the morphometric and meristic characteristics were conducted grey mullet, Mugil cephalus collected from wetland of Ogun waterside Local government Area, state, Nigeria. A total number ninety-one live specimens caught for a period March to June 2012. The fish immediately preserved ice in order slow down rate decomposition their length (TL) (cm), standard (SL) head (HL) body wid...
