Rapana venosa (Valenciennes 1846) (Gastropoda:
Muricidae), a mollusk native to Eastern Asia is reported for the
first time in Argentine waters in the north of Bahia Samborombon.
During a routine bottom sampling, a female specimen of 97.1 and
76.3 mm shell length and width, respectively, and egg capsules
were found approximately on 35.3 degreesS-55.4 degreesW in 13 m of
water. The possible way of entrance is discussed. The finding of
egg capsules permits the supposition that the introduced
population is sexually mature and actively breeding. The presence
of banks of mussels (Mytilus edulis platensis) and oysters
(Ostrea puelchana), probable prey, together with the
occurrence of the egg capsules point out that the development of
R. venosa in Argentina could be ecologically and
