Clam is a common name for several kinds of bivalve molluscs. The word is often applied only to those that are edible and live as infauna, spending most of their lives halfway buried in the sand of the seafloor or riverbeds. Clams have two shells of equal size connected by two adductor muscles and have a powerful burrowing foot. They live in both freshwater and marine environments; in salt water they prefer to burrow down into the mud and the turbidity of the water required varies with species and location; the greatest diversity of these is in North America.
Hector's beaked whale, is a small mesoplodont living in the Southern Hemisphere. This whale is named after Sir James Hector, a founder of the colonial museum in Wellington, New Zealand. The species has rarely been seen in the wild.
Actaea, commonly called baneberry, bugbane and cohosh, is a genus of flowering plants of the family Ranunculaceae, native to subtropical, temperate and subarctic regions of Europe, Asia and North America.
The giant clams are the members of the clam genus Tridacna that are the largest living bivalve mollusks. There are several species of "giant clams" in the genus Tridacna, which are often misidentified for Tridacna gigas, the most commonly intended species referred to as "the giant clam".
Haplogroup F is a human mitochondrial DNA (mtDNA) haplogroup. The clade is most common in East Asia and Southeast Asia. It has not been found among Native Americans.
The Veneridae or venerids, common name: Venus clams, are a very large family of minute to large, saltwater clams, marine bivalve molluscs. Over 500 living species of venerid bivalves are known, most of which are edible, and many of which are exploited as food sources.
Mercenaria is a genus of edible saltwater clams, marine bivalve molluscs in the family Veneridae, the Venus clams.
Chione cancellata, is a species of medium-sized saltwater clam, a marine bivalve mollusc in the family Veneridae, the venus clams.
The oriental trumpeter whiting is a widely distributed species of benthic inshore fish in the smelt-whiting family. The species ranges from east Africa to Japan, inhabiting much if the southern Asian and Indonesian coastlines. Its morphology is very similar to other species within the genus Sillago, with a long, compressed body and silvery overall colour. It can be distinguished from its relatives by colour patterns and particularly swim bladder morphology, which helps define most species of Sillago. S aeolus is a benthic predator, consuming a variety of crustaceans and polychaetes. As with most members of the smelt whiting family, it is important to small coastal fisheries in various areas of its range.
Toyotamaphimeia is a genus of extinct gavialid crocodylian which lived in Japan and Taiwan during the Pleistocene. A specimen recovered in 1964 at Osaka University during the construction of a new science building has been dated to around 430–380 thousand years old based on the stratum in which it was found. Toyotamaphimeia was a fairly large crocodylian measuring approximately 6.3–7.3 metres (21–24 ft) long. Two species are named, T. machikanensis from Japan and T. taiwanica from Taiwan, both originally described as members of the genus Tomistoma.
Lajonkairia lajonkairii is an edible species of saltwater clam in the family Veneridae, the Venus clams. Common names include Manila clam, Japanese littleneck clam, Japanese cockle, and Japanese carpet shell. In Japan, it is known as asari. In Korea, it is known as bajirak.
Meretrix lyrata, the lyrate Asiatic hard clam, also known simply as the hard clam, is an edible saltwater clam, a marine bivalve mollusc in the family Veneridae, the Venus clams.
Taenia asiatica, commonly known as Asian taenia or Asian tapeworm, is a parasitic tapeworm of humans and pigs. It is one of the three species of Taenia infecting humans and causes taeniasis. Discovered only in 1980s from Taiwan and other East Asian countries as an unusual species, it is so notoriously similar to Taenia saginata, the beef tapeworm, that it was for a time regarded as a slightly different strain. But anomaly arose as the tapeworm is not of cattle origin, but of pigs. Morphological details also showed significant variations, such as presence of rostellar hooks, shorter body, and fewer body segments. The scientific name designated was then Asian T. saginata. But the taxonomic consensus turns out to be that it is a unique species. It was in 1993 that two Korean parasitologists, Keeseon S. Eom and Han Jong Rim, provided the biological bases for classifying it into a separate species. The use of mitochondrial genome sequence and molecular phylogeny in the late 2000s established the taxonomic status.
Periglypta is a genus of bivalves in the subfamily Venerinae of the family Veneridae.
Meretrix is a genus of edible saltwater clams, marine bivalve molluscs in the family Veneridae, the Venus clams. They appeared in the fossil record in the Cenomanian age.
Tridacna noae, also known as Noah’s giant clam or the Teardrop giant clam, is a species of giant clam. Up until recently, T. noae was confused with the small giant clam Tridacna maxima, but is now known to be its own independent species. It has a broad distribution in the Indo-Pacific.
Paratapes undulatus, common name undulate venus, is a species of saltwater clam, a marine bivalve mollusk in the family Veneridae, the Venus clams.
Lioconcha hieroglyphica is a species of saltwater clam, a marine bivalve mollusc in the family Veneridae, the venus clams.
Meretrix taiwanica is a clam indigenous to Taiwan and China, it was misidentified as Meretrix lusoria until 2023.
Meretrix lamarckii, also called Korean clam or Korean hard clam, is a species of saltwater bivalve in the family Veneridae. It is the second species of venerid clam where doubly uniparental inheritance (DUI) has been identified.
