Inter- and intra-specific variations of snail meat nutritive value are well documented. The same may be true even within the same species variety. Both active and hibernating snails were collected from two distinct sites from geographical and subclimatic point of view. Using bidimensional data processing, statistical, and biochemical analyses we assessed the actions of environmental factors and metabolical status on intravariety changes of aperture morphological features and foot meat chemical composition. We demonstrated that aperture area tended to be larger in wetter areals whereas relationships between aperture height and foot weight sugested the lack of scientific background for calibration of wild snails. As regards the influence of metabolic status and location on foot chemical composition our results pointed to raw protein as possible predictor of genetic and environmental-induced biochemical variations within the same species variety while percentage content of raw protein in the total amount of dry matter displayed, regardless of origin, a relatively constant variation in relation to the metabolic status.
