The Lucinacea (Eulamellibranchia) have been studied and particular attention has been paid to the feeding, respiratory and cleansing currents and their relation to the morphology and habits of the
Frequency-dependent selection by predators.

Sometimes predators tend to concentrate on common varieties of prey and overlook rare ones. Within prey species, this could result in the fitness of each variety being inversely related to its
The family Kelliellidae (Bivalvia: Heterodonta) from the deep Atlantic and its relationship with the family Vesicomyidae
TLDR
It is concluded that the large, elongate, chalky shells of the genus Calyptogena and its relatives are distinct, at least, at subfamilial level.
The Morphology of Deep-Sea Thyasiridae (Mollusca: Bivalvia) from the Atlantic Ocean
TLDR
Twenty-five species and three subspecies of the family Thyasiridae (Bivalvia: Lucinacea) are described from the deep Atlantic, with the greatest reduction in size and greatest simplification of morphology seen in species of the subgenera Thyasira and Parathyasira.
The Functional Morphology of Atlantic Deep Water Species of the Families Cuspidariidae and Poromyidae (Bivalvia): An Analysis of the Evolution of the Septibranch Condition
TLDR
The Verticordiidae and Poromyidae are more closely related to one another than either is to the Cuspidariidae, and a new genus, Protocuspidaria, is identified on the basis of gross morphological differences.

  • 5 September 1974
TLDR
This study shows that the latter two families of the Verticordiidae have been derived from the Anomalodesmacea, and shows that most of the eighteen species have a stomach identical to that of the septibranch families, however, one or two species show limited ciliated surfaces intermediate in extent between the anomalodesmacean, as exemplified by Lyonsia, and the sePTibranch condition.
THE FUNCTIONAL AND ADAPTIVE MORPHOLOGY OF THE DEEP-SEA SPECIES OF THE ARCACEA (MOLLUSCA: BIVALVIA) FROM THE ATLANTIC
TLDR
Species of two genera, Bathyarca Kobelt (1891) and Bentharca Verrill and Bush (1898), occur beyond the shelf-slope break of the continental margins of the Atlantic and their morphology is conservative and differs little from shallow-water arcids.
