Atactodea striata, common name striated beach clam or striated little trough shell, is a species of surf clam, a marine bivalve mollusk in the family Mesodesmatidae.
Atactodea is the abundant, small, relatively strongly concentrically ribbed mesodesmatid. [1]
Found in atoll lagoons throughout the Indo-Pacific including Madagascar, India, Viet Nam, China, Philippines, Tarawa, Malaysia, Australia, Papua New Guinea, New Caledonia, Tuvalu, Fiji, Japan (up to Kii Peninsula, Honshu), and Vanuatu. [2] It has been introduced in the Mediterranean Sea in the areas of Israel and Malta. [3] [4]
Found in sandy substrates in the intertidal zone. [5] [6] This small surf clam may occur in abundance on high intertidal lagoon beaches. [7]
These clams are readily available by foraging the inshore tidal flats, mangroves and rocks. Archeological evidence indicates that Atactodea striata were used as a subsistence food by the Lapita, a Neolithic people of the South Pacific, at least as early as 4,700 years ago. [5] They are among the most common bivalves found in 2000 year-old shell middens in Papua New Guinea [8] and in more recent shell middens in Australia. [9] Called "Alure" in South Vanuatu Languages, Atactodea striata is harvested by the indigenous people of Vanuatu as a minor subsistence food. Atactodea striata is harvested, mostly by women, by gleaning intertidal zones. Women fishers walk the shoreline and shallows collecting Atactodea along with a variety of other common clams, bivalves, crabs, chitons, sea slugs, anemone and octopus. [10] On Tarawa, indigenous people harvest Atactodea striata as a preferred baby food because of its small size. [7]
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.
Bivalvia, in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class of marine and freshwater molluscs that have laterally compressed bodies enclosed by a shell consisting of two hinged parts. As a group, bivalves have no head and they lack some usual molluscan organs, like the radula and the odontophore. The class includes the clams, oysters, cockles, mussels, scallops, and numerous other families that live in saltwater, as well as a number of families that live in freshwater. The majority are filter feeders. The gills have evolved into ctenidia, specialised organs for feeding and breathing. Most bivalves bury themselves in sediment, where they are relatively safe from predation. Others lie on the sea floor or attach themselves to rocks or other hard surfaces. Some bivalves, such as the scallops and file shells, can swim. Shipworms bore into wood, clay, or stone and live inside these substances.
The Lapita culture is the name given to a Neolithic Austronesian people and their distinct material culture, who settled Island Melanesia via a seaborne migration at around 1600 to 500 BCE. The Lapita people are believed to have originated from the northern Philippines, either directly, via the Mariana Islands, or both. They were notable for their distinctive geometric designs on dentate-stamped pottery, which closely resemble the pottery recovered from the Nagsabaran archaeological site in northern Luzon. The Lapita intermarried with the Papuan populations to various degrees, and are the direct ancestors of the Austronesian peoples of Polynesia, eastern Micronesia, and Island Melanesia.
Tridacna gigas, the giant clam, is the most well-known species of the giant clam genus Tridacna. Giant clams are the largest living bivalve mollusks. Several other species of "giant clams" in the genus Tridacna, are often misidentified as Tridacna gigas.
The Pacific razor clam, Siliqua patula, is a species of large marine bivalve mollusc in the family Pharidae.
Scylla serrata is an ecologically important species of crab found in the estuaries and mangroves of Africa, Australia, and Asia. In their most common forms, their shell colours vary from a deep, mottled green to very dark brown.
Donax is a genus of small, edible saltwater clams, marine bivalve molluscs with highly variable color patterns. The genus is sometimes known as bean clams or wedge shells; however, Donax species have different common names in different parts of the world. In the southeastern U.S. they are known as "coquina", a word that is also used for the hard limestone concretions of their shells and those of other marine organisms. They are called "Chip Chip" in Trinidad & Tobago and "Chipi Chipi" in Venezuela, "Stumpfmuschel" in German, and "Zaaje" in Dutch. In South Vanuatu Languages they are called "Kaiwi" or "Tumbar".
The Nukumanu Islands, formerly the Tasman Islands, is an atoll of Papua New Guinea, located in the south-western Pacific Ocean, 4 degrees south of the Equator.
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).
Toke Atoll or Taka Atoll is a small, uninhabited coral atoll in the Ratak Chain of the Marshall Islands. It is one of the smaller atolls in the Marshalls and located at 11°17′N169°37′E. It is visited regularly by the residents of nearby Utirik Atoll.
The Atlantic surf clam, also called the bar clam, hen clam, skimmer or simply sea clam, is a very large, edible, saltwater clam or marine bivalve mollusk in the family Mactridae. It is one of the most commonly found species of bivalves in the western Atlantic Ocean. Able to reach sizes between 7.9 and 8.9 inches in length, Atlantic surf clams are much larger than Spisula solida, which also resides in the eastern Atlantic coastal waters. Atlantic surf clams reproduce in late summer, when the water temperatures peak.
Saxidomus nuttalli is a species of large edible saltwater clam, a marine bivalve mollusk in the family Veneridae, the venus clams. Common names include California butterclam and Washington clam.
The Solomon Islands (archipelago) is an island group in the western South Pacific Ocean, north-east of Australia. The archipelago is in the Melanesian subregion and bioregion of Oceania and forms the eastern boundary of the Solomon Sea. The many islands of the archipelago are distributed across the sovereign states of Papua New Guinea and Solomon Islands. The largest island in the archipelago is Bougainville Island, which is a part of the Autonomous Region of Bougainville along with Buka Island, the Nukumanu Islands, and a number of smaller nearby islands. Much of the remainder falls within the territory of Solomon Islands and include the atolls of Ontong Java, Sikaiana, the raised coral atolls of Bellona and Rennell, and the volcanic islands of Choiseul, Guadalcanal, Makira, Malaita, New Georgia, the Nggelas, Santa Isabel, and the Shortlands. The Santa Cruz Islands are not a part of the archipelago.
South Pacific is a British nature documentary series from the BBC Natural History Unit, which began airing on BBC Two on 10 May 2009. The six-part series surveys the natural history of the islands of the South Pacific region, including many of the coral atolls and New Zealand. It was filmed entirely in high-definition. South Pacific was co-produced by the Discovery Channel and the series producer was Huw Cordey. It is narrated by Benedict Cumberbatch. Filming took place over 18 months in a variety of remote locations around the Pacific including: Anuta, Banks Islands, French Frigate Shoals, Papua New Guinea, Palmyra, Kingman Reef, Tuvalu, Palau, Caroline Islands, Tuamotus and Tanna Island in Vanuatu.
