... Well,its hard to answer really,since Clams live a really long time... but whales live long too. In exchange for this plentiful supply, the clam offers the algae a safe home and regular access to sunlight for photosynthesis. The giant clam also feeds on the sugars and proteins produced by the billions of algae that live within its tissues. Credit: Vincenzo Lombardo/The Image Bank/Getty Images. From the pinhead-size specimens used in Vietnamese cooking to the giant guy that gave up its ghost to serve as decorations for Ivanka Trump’s Thanksgiving table, there are thousands of different species of clams that range in size, shape, and, of course, flavor.But, even as the food world rapidly globalizes, clams remain steadfastly regional. Since then, the giant clams have been studied in great detail. The Derasa Clam is the most widely available and hardy of the Tridacna; clams. Under the proper conditions, smaller Derasa Clams can double or triple their size in less than a year. Clam digging makes finding seams feel like childs play. Well, there are different types of clams...so they dont all live together. This massive clam has been recorded at a maximum length of 4.5 feet (137 cm) and can weigh up to 734 lbs (Knop 1996) once full grown. It is the largest clam of its genus, as well as the largest bivalve of all. Couple hours later and I had a whopping ONE clam gall. Besides for algae, giant clam often offers protection for pea crab. The giant, burrowing and horsehoof clams are found only in the central Indo-Pacific. Clams in the culinary sense do not live attached to a substrate (whereas oysters and mussels do) and do not live near the bottom (whereas scallops do). The Tridacna gigas clam is commonly called the Giant Clam or Gigas Clam. A ll of the species of clams in the family Tridacnidae are commonly called giant clams, but they actually vary a great deal when it comes to how large they can grow. Under the proper conditions, smaller Derasa Clams can double or triple their size in less than a year. For example, a large specimen of Tridacna crocea may be only four inches in length when measuring the shell from end to end, while its close cousin, T. maxima, often reaches eight inches in length. In culinary usage, clams are commonly eaten marine bivalves, as in clam digging and the resulting soup, clam chowder. The answer was:they live in various places. Giant clams are sedentary animals that are found in the relatively shallow water not more than 20 meters deep. This species is one of the largest of the "giant" clams, and grows rapidly, reaching a maximum size of approximately 20 inches. Of the 15,000 species of bivalves known as clams, some have life cycles of only one year. Where do they live? Giant Clam - Habitat Where Do Giant Clams Live? Giant clams live about 150 years while cold seep clams don't even reach maturity until they are 100. However, most species live between three and 10 years. The giant clams arent very plentiful, and I probably harvested a dozen and only got 1 ingrdient. Live clams may be stored for up to 10 days, and they should be kept in a shallow dish covered with a damp towel (but not water until ready to use). There is one question I found: Where do clams live?

This species is one of the largest of the "giant" clams, and grows rapidly, reaching a maximum size of approximately 20 inches. In culinary usage, clams are commonly eaten marine bivalves, as in clam digging and the resulting soup, clam chowder. Giant clams live in all of the marine parks in Western Australia’s north-west, in protected shallow water areas on the shore side of coral reefs. The largest known specimen of the giant clam, till date, was found in 1817, off the north-western coast of Sumatra. Giant clams can live up to one hundred years. Clams do not encroach on other reef tank species in the way that often corals do, and offer peace of mind as well as beauty for their keepers. I decided to go try and farm those so I could make some of the food. If they’re alive, they’ll close. Tridacna Clams are relatively slow growing reef aquarium inhabitants, a trait that is actually considered a positive feature by most advanced reef tank hobbyists. How Long Do Clams Live? Clam juice is the real grind of summerset. Once a young clam larvae finds a suitable location on the reef it attaches itself to the reef and stay there for the rest of its life.
