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".
Extinct species within this genus include: [4]
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.
The Pacific geoduck is a species of very large saltwater clam in the family Hiatellidae. The common name is derived from the Lushootseed name, gʷidəq.
Panopea abrupta is an extinct species of large marine bivalve mollusc in the family Hiatellidae. Between 1983 and 2010, this species of clam was confused with the Pacific geoduck, Panopea generosa, in the scientific literature.
Tresus capax is a species of saltwater clam, marine bivalve mollusk, common name the fat gaper, in the family Mactridae. It also shares the common name horse clam with Tresus nuttallii a species which is similar in morphology and lifestyle. Both species are somewhat similar to the geoduck, though smaller, with shells up to eight inches long (20 cm), weight to 3–4 lb (1.4–1.8 kg).
Dosinia is a genus of saltwater clams, marine bivalve molluscs in the family Veneridae, subfamily Dosiniinae Deshayes, 1853. The shell of Dosinia species is disc-like in shape, usually white, and therefore is reminiscent of the shells of Lucinid bivalves.
Barbatia is a genus of "bearded" ark clams, marine bivalve mollusks in the family Arcidae, the ark clams.
Nucula is a genus of very small saltwater clams. They are part of the family Nuculidae.
Hiatellidae is a taxonomic family of saltwater clams, marine bivalve molluscs. This family is placed in the order Adapedonta.
Clanculus is a genus of sea snail, marine gastropod molluscs of the family Trochidae, the top shells.
Homalopoma, common name the dwarf turbans, is a genus of mostly very small sea snails with a calcareous operculum, marine gastropoda molluscs in the subfamily Colloniinae of the family Colloniidae.
Spisula is a genus of medium-sized to large marine bivalve mollusks or clams in the subfamily Mactrinae of the family Mactridae, commonly known as surf clams or trough shells.
Panopea zelandica, commonly known as the deepwater clam or New Zealand geoduck, is a large species of marine bivalve mollusc in the Panopea (geoduck) genus of the family Hiatellidae. It is also sometimes called a king clam, or a gaper – in reference to the shell not being closed at either end.
Cerithium is a genus of small to medium-sized sea snails, marine gastropod molluscs in the family Cerithiidae, the ceriths.
Crepidula, commonly known as the slipper snails, slipper limpets, or slipper shells, is a genus of sea snails, marine gastropod mollusks in the family Calyptraeidae. This family includes the slipper snails (Crepidula), hat snails (Calyptraea), spiny slipper snails (Bostrycapulus), and cup-and-saucer snails (Crucibulum) as well as Crepipatella, Siphopatella, Grandicrepidula, and Maoricrypta.
Dentalium is a large genus of tooth shells or tusk shells, marine scaphopod molluscs in the family Dentaliidae. The genus contains 50 described species and about 50 extinct species.
Calyptraea, commonly known as the Chinese hat snails is a genus of sea snails, marine gastropod mollusks in the family Calyptraeidae, a family which contains the slipper snails or slipper limpets, cup-and-saucer snails, and Chinese hat snails.
Rangia is a genus of bivalve molluscs or clams in the subfamily Mactrinae of the family Mactridae.
Panopea glycimeris is a species of large marine bivalve mollusc in the family Hiatellidae.
Paphia is a genus of saltwater clam, a marine bivalve mollusk in the subfamily Tapetinae of the family Veneridae, the Venus clams.
Solecurtus is a genus of saltwater clam, a marine bivalve molluscs in the family Solecurtidae.
Panopea bitruncata is a species of marine bivalve commonly known as the Atlantic geoduck or Atlantic geoduck clam. These clams like their more famous Pacific relative P. generosa have an enlarged siphon that can extend to great lengths or contract to just barely poke out of the shell. They are generally smaller in comparison to the Pacific species though still constitute a sizable mollusc as they cannot fully retract their siphon.
