Rostroconchia: A New Class of Bivalved Mollusks
Science, 1972Four Paleozoic bivalved genera are assigned to the new molluscan class Rostroconchia: Eopteria, Euchasma, Conocardium , and Pseudoconocardium . These mollusks have an uncoiled univalved larval shell; an untorted bivalved adult shell; no hinge teeth, ligament, or adductor muscles; and a fused,

Publisher Summary This chapter focuses on the rearing of bivalve mollusks. The rearing of larval and juvenile bivalves requires an adequate supply of sea water of proper salinity and free of substances that may interfere with their normal development.

Acrosomal ATPase in starfish and bivalve mollusk spermatozoa
Experimental Cell Research, 1973Abstract ATPase activity was found in acrosomes of starfish and bivalve mollusk spermatozoa, using a cytochemical method with electron microscopy. The activity was located in central material of the starfish acrosome and in material lining the acrosomal membrane of the Mytilus acrosome, as well as in the basal part of the starfish acrosome.

The impact of microplastics on bivalve mollusks: A bibliometric and scientific review
Marine Pollution Bulletin, 2023Bivalves are important members of the ecosystem and their populations are declining globally, making them a concern for their role in ecosystem services and the fishing industry. Bivalves are excellent bioindicators of MPs pollution due to their widespread distribution, filtering capabilities, and close association with human health. Microplastics (MPs)

Environmental and Evolutionary Stability in Bivalve Mollusks
Science, 1974There is no relationship between environmental stability [as indicated by infaunal (stable) versus epifaunal (unstable) habits] and the generic duration of extinct marine bivalve mollusks when the effects of cosmopolitanism (which is associated with long generic durations) and other paleontological "noise" are excluded.

Succinate and lactate oxidoreductases of bivalve mollusks
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1975Abstract 1. 1. Succinic acid is a major end product of anaerobic glycolysis in mollusks, and lactic acid is a minor product. On the hypothesis that production of these acids is partially controlled by properties of the enzymes catalyzing the final step in each pathway, extracts of the adductor muscle were prepared and used in oxidoreductase ...

Bivalve Mollusks: Fluid Dynamics of Burrowing
Science, 1966When bivalves burrow into soft substrates the foot is first extended and then dilated to obtain a firm anchorage before retraction pulls the shell downward. Pedal dilation is principally caused by adduction of the valves. The hinged shell functions as a hydraulic machine in which the strength of the adductor muscles is transferred to the distal part of

Exploring Satellite DNAs: Specificities of Bivalve Mollusks Genomes
2021Noncoding DNA sequences repeated in tandem or satellite DNAs make an integral part of every eukaryotic genome. Development and application of new methodological approaches through time enabled gradual improvement in understanding of structural and functional roles of these sequences, early misconsidered as "junk DNA".

Bivalve Mollusks: Control of Microbiological Contaminants
BioScience, 1982Historically, shellfish made a significant contribution to the American diet. Early inhabitants found abundant supplies of bivalve mollusks that could easily be harvested year-round. Shellfish, along with an ample supply of fish, provided high quality protein with little effort or cost to the consumer.

[Gonad innervation in bivalve mollusks].
Arkhiv anatomii, gistologii i embriologii, 1983In marine Lamellibranchia--Patinopecten yessoensis (Jay) and Crenomytilus grayanus (Dunker)--neural cells, small ganglia and neural fibres have been revealed in the gonad wall. The sensitive and effector parts are presented by rather variable morphological formations.
