The anomuran crabs of the family Albuneidae Stimpson, 1858 are specialized forms, living buried in sand. Because of their preferred habitat, they are very rarely encountered, and thus have been poorly studied in general (Osawa & Fujita 2012). They are commonly called “Sand crabs” (Boyko 2002). Worldwide, the Albuneidae family currently includes 48 species belonging to nine genera (Boyko & McLau...

This study aims to determine the relationship between hemocyte count and types with environmental variables morphometric measurements in Carcinus aestuarii. A total of 240 crabs were seasonally collected Çardak Lagoon June 2018, October February 2019, May 2019. The average carapace length (CL) was 44.66±0.44 mm, mean width (CW) 37.71±0.38 mm weight 28.49±0.88 g. Crab specimens anesthetized on i...

Abstract. Fauziyah, Mustopa AZ, Fatimah, Purwiyanto AIS, Rozirwan, Agustriani F, Putri WAE. 2021. Morphometric variation of the horseshoe crab Tachypleus gigas (Xiphosura: Limulidae) from Banyuasin estuarine South Sumatra, Indonesia. Biodiversitas 22: 5061-5070. Morphological studies are essential for fish resource management, ecology, conservation, and stock assessment. This research was condu...

Stock assessment and reproductive biology of the blue swimming crab, Portunus pelagicus, in Bandar Abbas coastal waters was conducted from August 2006 to July 2007. A total of 424 male and 348 female crabs were taken to the laboratory for length, weight and reproductive biometry. Estimate of growth parameter of crab showed t asymptotic carapace width (CW) was 172.5 mm, the curvature parameter, ...

Despite their broad occurrence in Australian basins, lower-level taxonomy of Early Cretaceous plesiosaurs is hindered by the scarcity skulls and other diagnostic elements. This paper presents a morphological morphometric analysis vertebrae comparison with selected non-Australian elasmosaurids (basal elasmosaurs, styxosaurines, aristonectines). Biometric involved measurements that include centru...

genus acomys comprising 14 species from mouse like rodents and substituted in murinae subfamily. the aim of this research was surveying external, cranial and dental character differences among diverse populations of acomys dimidiatus in minab, boushehr and geno biosphere reserve. sampling was performed during summer 2003 and 2005. total of 52 species were collected from mentioned sites. the res...

size at sexual maturity and patterns of somatic growth are important aspects of reproductive history of crab. the main purpose of this study is to provide an estimate for the onset of morphological sexual maturity in mangrove crab, opusia indica from a population located in korangi creek intertidal mud flat (karachi, pakistan) based on relative growth. the crabs were monthly collected through q...

Genetic selection in primary broiler breeders may modify skeletal structure, possibly impeding semen transfer, and could alter the size and degree of fluctuating asymmetry (FA) of bilateral traits associated with fertility. Hence, we hypothesized specific morphometric traits could predict differential fertility. Sixty primary broiler breeder males from Strains A and B (n = 30/strain) were indiv...

this study was carried out in order to determine the leave characteristics of some chestnut genotypes in the central black sea region of turkey and also to determine whether the leaf morphometric characteristics could be used for differentiation of genotypes. in this study, seven chestnut (castanea sativa mill.) genotypes (sa5-1, se 3-12, se 21-2, se 21-9, 552-8, 556-7 and 556-8) and one cultiv...

Some morphometric and biological characteristics of a European spider crab, Maja squinado (Herbst, 1788) caught off Aksaz region, (Biga, Çanakkale, Türkiye) were investigated. In addition, an epizoic species infesting this M. specimen has been identified. The crab was by commercial fisherman using trammel nets. Carapace length, carapace width weight the 15.9 cm, 14.5 1109 g respectively. oviger...
