[1] Later, the Icelandic researchers on the cruise which discovered the clam named it Hafrún, a woman's name which translates roughly as 'the mystery of the ocean'; taken from haf, 'ocean', and rún, 'mystery'.

The maxima clam has the largest geographical distribution among giant clam species; it may be found off high- or low-elevation islands, in lagoons or fringing reefs. [7] Its rapid growth rate is likely due to its ability to cultivate algae in its body tissue. [6]: 10 Although larval clams are planktonic, they become sessile in adulthood. [8]
Mercenaria is a genus of edible saltwater clams, marine bivalve molluscs in the family Veneridae, the Venus clams. [1]Left valve interior of Mercenaria mercenaria. The genus Mercenaria includes the quahogs, consisting of Mercenaria mercenaria, the northern quahog or hard clam, and M. campechiensis, the southern quahog.
A quahog can get quite old, each line on its shell is a growth ring. You can count the rings to determine the quahog’s age. Researchers estimate that the largest quahogs (about four inches in ...
The researchers found that Tridacna gigas (the best-known giant clam species) had become locally extinct in many areas. To make matters worse, “We found that over 80% of the locations where the ...
The largest RI quahog: Boy digs up biggest one ever found, then gives it away. The clam, nicknamed Little Rhody, came in at 5.75 inches across and weighed 2 pounds, 7.75 ounces.
The southern giant clam is a popular food item and aquarium species, and has therefore been hunted extensively throughout its natural habitat. [6] However, specimens traded today tend to be the result of aquaculture farms rather than wild-caught individuals, because the southern giant clam was one of the first clams to be bred commercially.

Sometimes the giant clams are still treated as a separate family Tridacnidae, [1] but modern phylogenetic analyses included them in the family Cardiidae as a subfamily. [2] [3] Two recent genera and eight species are known: Hippopus—2 species; Tridacna—10 species; Recent genetic evidence has shown them to be monophyletic sister taxa. [4]
