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.

Description

[edit]

Atactodea is the abundant, small, relatively strongly concentrically ribbed mesodesmatid.[1]

Distribution

[edit]

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]

Habitat

[edit]

Found in sandy substrates in the intertidal zone.[5][6] This small surf clam may occur in abundance on high intertidal lagoon beaches.[7]

Human use

[edit]

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]
