Mya arenaria has a high fecundity and reproductive potential but larval supply is sporadic and juvenile mortality is high, so that although, large numbers of spat may settle annually, successful recruitment and hence recovery may take longer than a year.
The observed regional differences in juvenile and adult M. arenaria could result from a lack of competent larvae over eastern versus southern Maine tidal flats in the form of either local effects (e.g., postponing metamorphosis to avoid settling on flats characterized by pollution, contamination, or otherwise unattractive habitat qualities until they are carried elsewhere) or regional effects associated with fewer M. arenaria larvae …

However, the taxonomic history of this species includes many synonyms, overlapping descriptions, and/or subspecies (e.g. Mya hemphilli, Mya arenomya arenaria, Winckworth 1930; Bernard 1979). The subgenera of Mya (Mya mya, Mya arenomya) For juvenile individuals of M. arenaria and potentially other bivalves, Steamer may be a candidate biomarker for exposure to ocean acidification conditions.

Shell length of juveniles rarely exceeded 2 mm in 1995, which was most For 1.8-2.8 mm shell length Mya arenaria clams, pumping rates ranged 0.03-0.22 μl s-1, inhalant siphon Reynolds numbers (Re) ranged 0.16-0.79 and mean inhalant velocities ranged 0.8-3.2 mm s-1 Owing to the low Re at which they pump and the small diameters of their siphons, juvenile clams are subject to unique hydrodynamic challenges, including high siphon resistance and susceptibility to refiltration. in suspension feeding by juvenile Mya arenaria clams Kevin T.

Often the population is dominated by one or two widely separated cohorts (Ayers, 1956; Möller & Rosenberg, 1983; Jones et al., 1989; André & Rosenberg, 1991; Kube, 1996; Strasser et al., 1999, 2003).
