The reproductive cycle of the Thecosomatous pteropod Limacina retroversa in the western South Atlantic
The reproductive cycle of Limacina retroversa in the Argentine Sea was studied by gonadal analysis. Samples were collected in 1978-1979. The relation between gonadal maturity and size is dependent on the season and the geographical area. Evidence of in situ reproduction was found at the beginning of...
