Panopea is a genus of large marine bivalve molluscs or clams in the family Hiatellidae.[1] There are 10 described species in Panopea.[1] Many of them are known under the common name "geoduck".

Extant species

  • Panopea abbreviata (Valenciennes, 1839) – southern geoduck
  • Panopea australis (G.B. Sowerby I, 1833)
  • Panopea bitruncata (Conrad, 1872)
  • Panopea generosa Gould, 1850 – Pacific geoduck
  • Panopea globosa Dall, 1898 – Cortes geoduck
  • Panopea glycimeris (Born, 1778)
  • Panopea japonica Adams, 1850 – Japanese geoduck[2]
  • Panopea smithae Powell, 1950
  • Panopea zelandica Quoy & Gaimard, 1835 – deepwater clam[3]

Extinct species

Fossil shell of Panopea intermedia

Extinct species within this genus include:[4]

  • Panopea abrupta (Conrad, 1849) (extinct Miocene fossil)[5]
  • Panopea depressa Martin 1859
  • Panopea dockensis Olsson and Petit 1964[6]
  • Panopea elongata Conrad 1835
  • Panopea gastaldii Michelotti 1861
  • Panopea gurgitis Brongniart, 1822
  • Panopea intermedia Sowerby 1814
  • Panopea mackrothi Geinitz 1857
  • Panopea montignyana Martin 1859
  • Panopea orientalis Forbes 1846
  • Panopea remondii Gabb 1864
  • Panopea toulai Lundgren 1895
  • Panopea vaudini Deshayes 1857

The fossil record of the genus dates back to the Cretaceous (and maybe the Triassic) (age range: 242.0 to 0.012 million years ago). These fossils have been found all over the world.
