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

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...
