The egg capsules, eggs and embryos of the muricid gastropod Coronium coronatum are described for the first time. Capsules are sessile, bulliform, semi-circular, with a plug in the dorsal center. Sutures split the capsule ...

The morphology and the deposition periods of egg capsules by the bruised nassa Nassarius vibex were investigated on two beaches located on the southeast coast of Brazil. The nassariids were associated with the charru mussel ...

The egg capsules, eggs and embryos of the muricid gastropod Trophon acanthodes are described for the first time. Egg capsules are sessile, bulliform, semi-circular, about 20 mm in diameter, with a plug in the centre of the ...

The reproductive biology of the nassariid Buccinanops paytensis is considered and compared with the other species in the genus. In B. paytensis an average of 42 egg capsules were attached to the shell of each female. A ...

Large-scale patterns of encapsulated embryo development and causal factors determining developmental success in the marine environment have been relevant issues of research for decades. We studied the embryonic development ...

South American volutids are very homogeneous with regard to their reproductive mode. These gastropods generally spawn egg capsules containing few eggs; the embryos feed on substances contained in the intracapsular fluid ...

The buccinid Americominella longisetosa (Castellanos and Fernández, 1972) is widely distributed along the Southwestern Atlantic shelf where it is found at 200–1,250 m depth. A total of 38 egg capsules of this species were ...
