Invasion

Invasion Description

1st Record: AK/Hooper Bay, Bering sea (1924, Baxter, personal communication, cited by Carlton 1979)

The presence of several similar species (M. truncata, M. baxteri, M. pseudoarenaria, Panomya priapus) in Alaska waters, as well as fossil and subfossil specimens of M. arenaria in shell deposits is a problem for interpreting early records of this species in Alaska, particularly records north of the Alaska Peninsula (Bernard 1979; Carlton 1979; James T. Carlton, personal communication 2012). Carlton considers this species to be probably absent from the Chukchi Sea, but a likely future invader. ''Records from at least southern Alaska and north (if not further south) should be genetically confirmed as Mya arenaria or Mya japonica (see text) Carlton 2023a)
