Body size is a crucial metric that is often obtained during the breeding migration of female land crabs. Most commonly, these measurements are obtained by hand but hand-measuring them carries risks for both crabs and researchers. In this study, we developed a novel “photo-image approach” to measure the maximum carapace width of Cardisoma carnifex (Herbst, 1796) in the field, and compared the results with hand measurements. We found a significant relationship in the maximum carapace width measured between the two approaches (Linear regression,
La taille du corps est une mesure importante qui est souvent prise au cours de la migration des crabes terrestres pour la reproduction. Le plus souvent, ces mesures sont faites manuellement mais ce procédé comporte des risques à la fois pour les crabes et pour les chercheurs. Dans cette étude, nous développons une nouvelle “approche par photo-image” pour mesurer la largeur maximale de la carapace chez Cardisoma carnifex (Herbst, 1796) sur le terrain et nous avons comparé les résultats avec ceux obtenus avec des mesures manuelles. Nous avons trouvé une relation significative dans la mesure de la largeur maximale de la carapace entre les deux approches (Linear regression,
