Biometrics of Nassarius mutabilis (l.) (Gasteropa, Nassaridae) in the Central Adriatic Sea

Shell height, shell diameter, total weight and fresh meat weight were measured on specimens of Nassarius
mutabilis (L.) collected with a dredge at two different depths in the central Adriatic sea. The results obtained
separately for the two sexes showed that females generally have a higher shell height and that, starting from
a certain size, they tend to become more globular and heavier than males.
