Spawn and reproduction of the gastropod Trochita pileus (Lamarck, 1822) from the southwestern Atlantic Ocean

Mostrar todas las versiones(3)

Specimens and eggs masses of the gastropod Trochita pileus were collected during a research cruise by bottom trawling at depths between 82 m and 120 m. Adult T. pileus were found attached to such hard substrata as the shells of scallops and oysters. The egg mass of T. pileus is composed of 7-8 trans...
