In this paper, we report surveys of allozyme variation in
Tridacna maxima populations sampled throughout the species range in the west Pacific from Australia to Polynesia to test [TABULAR DATA FOR TABLE 1 OMITTED] whether the northwest to southeast trend in gene flow perpendicular to major surface currents found in T.
(1988) studied gonad maturation of the giant clam
Tridacna gigas (Linnaeus, 1758) (subfamily Tridacninae) by qualitatively characterizing the maturity stages of male and female tissues.
In the Fatu-ma-Futi assemblage, several of the largest taxa, such as
Tridacna, Turbo, and Trochus are found living on the hard substrate or nearby coral sand of coral reef habitats.
(2006) examined how light intensity and water temperature influence the symbiosis rates of
Tridacna crocea,
Tridacna derasa, and
Tridacna squamosa.

Meanwhile, log-phase cultures of the following isolates of Symbiodinium were harvested and washed in FSW by centrifugation at 1000 X g for 5 mm: (1) TC2A, a clonal isolate from the tridacnid clam
Tridacna crocea (see isolate PHQU TC2A from Baillie et al., 1998); (2) HH2A, a clonal isolate from the tridacnid clam Hippopus hippopus (see isolate PHSC HH2A from Baillie et al., 1998); (3) HA3-5, a clonal isolate of a free-living isolate from Hawaiian subtidal sands (see Carlos et al., 1999); (4) CS164, a clonal isolate from the anemone Aiptasia tagetes (culture purchased from the Commonwealth Scientific and Industrial Research Organisation [CSJRO], Australia); and (5) CS 156, a clonal isolate from the stony coral Montipora verrucosa (culture purchased from CSIRO).

From 1976 onwards (Green 1976, 1979, 1991a: Table 3) two
Tridacna marine shell radiocarbon determinations have been available as an indication of the approximate age of the SE-SZ-8 dentate-decorated Lapita site of Nanggu, on the island of Nendo or Santa Cruz, in the Outer Eastern Islands of the Solomons.
These bivalves include all of the species in the subfamily Tridacninae, including the well-known genera of larger clams,
Tridacna and Hippopus, as well as less well-known genera of much smaller clams in the subfamily Fraginae, such as Corculum and Fragum (Kawaguti, 1950, 1983; Schneider, 1998).
The biggest clam in the nursery is a 98.3-centimeter long
Tridacna gigas and the shortest is a 3-cm juvenile.
In addition, no basophilic granulocytes were observed in the giant clam (
Tridacna crocea) (Nakayama et al.
