Ruditapes philippinarum, the Manila clam,[1] is an edible species of saltwater clam in the family Veneridae, the Venus clams.[2][3]
Description
The shell of Ruditapes philippinarum is elongate, oval, and sculptured with radiating ribs.[4] It is generally 40 to 57 millimeters wide, with a maximum width of 79 millimeters.[5]
Distribution
This clam is native to the coasts of the Indian, Philippines and Pacific Oceans from Pakistan and India north to China, Japan, Korea and the Kuril Islands.[6] It has an extensive nonnative distribution, having been introduced accidentally and purposely as a commercially harvested edible clam. It is now permanently established in coastal ecosystems in many parts of the world.[7]
Habitat
This burrowing clam is most abundant in subtropical and cooler temperate areas. It can be found in shallow waters in substrates of coarse sand, mud, and gravel.[5] It lives in the littoral and sublittoral zones.[8] It burrows no more than about 10 centimetres into the substrate. It sometimes lives in eelgrass beds.[8]
This species lives in many types of habitat, being found in the intertidal zone, brackish waters,[8] estuaries, and under ice. It survives in a range of salinities and temperatures, with narrower ranges required for breeding.[5]
Biology and ecology
This clam may become sexually mature in its first year of life, when it reaches about 15 millimeters in width, especially in warmer areas such as Hawaii. In cooler areas it begins breeding at older ages and larger sizes. In warmer regions it spawns year-round, but only in the summer in cooler areas. The fecundity of the species increases with size, a 40-millimeter female producing up to 2.4 million eggs.[5]
