Unique evolution of Bivalvia arginine kinases

Cellular and Molecular Life Sciences (CMLS), 2004
The clams Pseudocardium, Solen, Corbicula and Ensis possess a unique form of arginine kinase (AK) with a molecular mass of 80 kDa and an unusual two-domain structure, a result of gene duplication and subsequent fusion. These AKs also lack two functionally important amino acid residues, Asp(62) and Arg(193), which are strictly conserved in other 40-kDa ...

Adaptations to tube dwelling in the Bivalvia

Lethaia, 1982
Tube-dwelling Bivalvia, which enclose themselves in secondary calcareous envelopes (crypts), evolved polyphyletically within the Gastrochaenacea, Pholadacea and Clavagellacea. The adaptive strategies for maintaining a suitable life position within a soft sediment were the main factor affecting the evolution of these forms.

Statocyst structure in the Anomalodesmata (Bivalvia)

Journal of Zoology, 1985
Statocyst structure in representatives of each, as currently recognized, family of the bivalve sub‐class Anomalodesmata has been investigated.Three types are recognized—A, B and C. Type A is possessed only by Pholadomya Candida, a representative of the ancient Pholadomyacea. Type C is found only in the Cuspidariacea.
