“…The maximum age of A. kagoshimensis (7 years) was recorded in the population of the eastern part of the Anatolian coast (Sşahin et al 2009), and the greatest length of the Black Sea specimens (up to 85 mm) was also recorded there (Sşahin et al 2009). The length of the A. kagoshimensis was in the range of 4.5-71.8 mm in the Middle Black Sea (Aydin et al 2014). On the Caucasian coast and off the coast of Bulgaria, the length of the A. kagoshimensis shell did not exceed 60 mm (Marinov 1990;Zolotarev and Terentyev 2012), in the Kerch Strait -65 mm (Anistratenko and Haliman 2006).…”

Features of shape and size variability of blood ark (Anadara kagoshimensis) inhabiting biotopes in the northern part of the Black and Azov Seas were studied. Fourteen morphometric traits were measured for each blood ark shell. The principal component analysis extracted only one principal component (PC) whose eigenvalue is greater than 1.0. The PC 1 explained 84.5 % of the variation in morphometric traits and was interpreted to be an integral indicator of mollusk shell size. The variation of morphometric traits due to the size and asymmetry of the valves was subjected to correction using a Multiple General Linear Model with PC 1 as a continuous predictor and right or left valve as a discrete predictor. A cluster analysis was performed based on the residuals after size correction, as a result of which mollusk individuals were divided into four clusters. For mollusks from the Sea of Azov, a characteristic feature was an increased distance between pallial line and ventral shell margin. In turn, mollusks from the Black Sea exhibited an increase in the width of the posterior adductor scar. The observed morphological differences can be explained by different quantity and quality of food, since the soil composition in the biotopes studied is almost identical.

“…Due to the fact that shell is the most variable part of a bivalve species and is largely affected by environmental conditions (Uba et al, 2019), it has been the most widely used part in studying Anadara species, specifically by focusing on shell shape variation. Succeeding studies in Anadara species supported significant shell shape variation within and between populations (Mzighani, 2005;Faulkner, 2010;Lodola et al, 2011;Finogenova et al, 2013;Souji & Radhakrishnan, 2015;Aydin et al, 2014;Qonita et al, 2015;Meshram & Mohite, 2016). These studies, among others, focused on traditional approaches in morphometric studies (i.e., analysis of linear distances).…”

The advent of geometric morphometrics opened an area to study morphological variations in organisms. Thus, the aim of this study is to use outline-based geometric morphometrics to describe variations in the shell shapes of the left and right valves of Anadara oceanica (Lesson, 1831) (Bivalvia Arcidae) populations from the two neighbouring intertidal zones of Margosatubig, Zamboanga del Sur, Philippines. Herein, there were two levels of analyses that were employed: first, the shell shapes of the outer left and right valves between populations were compared; second, the shell shapes within population were quantitatively determined in terms of its symmetry. Results revealed significant variations both in the left and right valves of A. oceanica between populations. The variations observed are characterized by the deformations in the umbonal and anteroventral angles and in the dorsal, anterior and ventral margins of the outer shell both in the left and right valves. Although further studies are necessary in order to elucidate these variations, the second analysis revealed that the detected asymmetry in the shell shapes within A. oceanica populations was the cause of variation within populations that contributed to the significant variations between populations. Considering that the two sites are not geographically isolated, the results herein clearly proved that shell shape variation could also occur in neighbouring populations. The variations in the shell shapes of A. oceanica populations may have implications to habitat adaptation which aid in understanding the nature of this species especially those dwelling in the intertidal areas of Margosatubig,

“…Correlations among the morphometric parameters are of particular significance in terms of understanding of smoothness of organism shell structure. It should be underlined, however, that big sample sizes could make a slight difference among the correlations that are significant (Aydın et al, 2014). The relationship of SL with TW and the linear relationship of SL with SWi and SH are presented in Figure 5.…”

Limpets are common inhabitants of the midlittoral and upper infralittoral zones and play an important ecological role in the coastal ecosystem. The study aimed to assess growth, meat yield, morphological aspects, condition and reproduction features of Patella caerulea. About 58% of collected Mediterranean limpets were concentrated in the 25.0-34.9 mm shell length group. The average meat yield ratio was calculated as 39.34%. Mean growth increments for shell length (SL) and total weight (TW) were 23.99% and 97.99%, respectively. Results exhibited relatively high correlation coefficients among variables. Mean condition factor value was calculated as 14.2. Spawning occurs over a short period with ovigerous females observed on two month periods. Mean fecundity was calculated as 90,983±28,675 eggs/g whereas mean egg diameter was estimated as 160.6 μm. This study presents first baseline information about biological and morphological of Mediterranean Limpets population in Black Sea.
