Abstract

Body dimensions are used to identify and characterize individuals of a large
variety of species, and may be evaluated in individuals that are parasitized or not
regarding specific somatic responses. This paper presents a study of 1,129 snails of
Biomphalaria, collected in 2004 in the municipality of Juiz de Fora, Minas Gerais,
Brazil. The following species were captured: 360 specimens of B. straminea (215
evaluated), 255 of B. peregrina (196 evaluated) and 1,555 of B. tenagophila (718
evaluated). The latter was the most prevalent species of this genus in the region. The
captured snails were dried, weighed and measured alive. The weight and size for
each species was evaluated in an independent and correlated form. From a statistical
standpoint, the size and weight variables revealed that B. peregrina had the smallest
biometric measures, followed by B. straminea and B. tenagophila in increasing
order. All the species had maximum shell diameters around 50% smaller than
those described in the literature. There was a strong positive correlation between
the weight (body mass) and size (shell diameter) in all the species, giving a solid
basis for a consistent correlation between weight and diameter in the Biomphalaria
species found in the municipality.
