Abstract:
Morphometrical relationship in the barnacle's species Striatobalanusamarylis has been studied in relation to variation in shapes, sizes, colours and ornamentations. The present study was designed to identify morphometric relationship of species Striatobalanusamarylis and to quantify traits of evolutionary significance by detecting changes in shape and function. Specimens were collected from Sonmiani beach during the months of November 2021 to February 2022. Shell of the specimens tubulo-conical in shape; orifice moderately large, pentagonal and toothed; surface smooth, pinkish purple with yellowish tint; lower half very lighter in colour, usually white. Parities solid, nonporous, articular ridge blunt and slightly prominent. Tergum long, with apex forming a slight beak. The following measurements of the shell were taken on each individual: the length of the basis along the carinorostral axis (LBA), the width of the basis (WBA), the length of the orifice along the carinorostral axis (LOR), the width of the orifice (WOR), the height of the carina (HTC), and the average thickness of the shell wall (TKC). These parameters have continued to be used as an estimate of size and in this study, the height of the carina ranged 11 mm - 27 mm, the height of the rostrum ranged 4 mm - 9 mm and the basal diameter of shell ranged from 6 mm - 11 mm. The derived morphometric measurements revealed the significant differentiation and accurate measurements between species by using allometric and statistical data.
