Geometric morphometric studies allowed to compare different morphological and anatomical part of the blue crab, Callinectes sapidus, in order to view the differences between the individuals regarding sex, size in maturity and size in different stages of development. Specifically, geometric morphometrics of the carapace width and length, abdomen, claws and paddles of 150 crabs were studied. Digital photographs were taken for each anatomical part and analysed through 24 landmarks and linear measurements. The results show that there is sexual dimorphism and allometric growth
Gli studi di morfometria geometrica hanno permesso di confrontare diverse parti morfologiche e anatomiche del granchio blu, Callinectes sapidus, al fine di visualizzare le differenze tra gli individui per quanto riguarda il sesso, la taglia a maturità e la taglia nei diversi stadi di sviluppo. In particolare, sono state studiate la larghezza e la lunghezza del carapace, dell'addome, delle chele e delle paddle di 150 granchi. Sono state scattate fotografie digitali per ogni parte anatomica e analizzate attraverso 24 landmark e misurazioni lineari. I risultati mostrano che vi è dimorfismo sessuale e crescita allometrica.

Abstract
Geometric morphometric studies allowed to compare different morphological and anatomical part of the blue crab, Callinectes sapidus, in order to view the differences between the individuals regarding sex, size in maturity and size in different stages of development. Specifically, geometric morphometrics of the carapace width and length, abdomen, claws and paddles of 150 crabs were studied. Digital photographs were taken for each anatomical part and analysed through 24 landmarks and linear measurements. The results show that there is sexual dimorphism and allometric growthFile | Dimensione | Formato | |
