The two extant genera of Tridacninae, Hippopus, and Tridacna, contain 12 recognized species (ter Poorten 2015a, 2015b): Hippopus hippopus (Linnaeus, 1758), Hippopus porcellanus (Rosewater, 1982), Tridacna crocea (Lamarck, 1819), Tridacna derasa (Roding, 1798), Tridacna gigas (Linnaeus, 1758), Tridacna maxima (Roding, 1798), Tridacna mbalavuana (Ladd, 1934), Tridacna ningaloo (Penny & Willan, 2014), Tridacna noae (Roding, 1798), Tridacna rosewateri (Sirenko & Scarlato, 1991), Tridacna squamosa (Lamarck, 1819), and Tridacna squamosina (Sturany, 1899).
Given the low numbers of Tridacna gigas, Tridacna squamosa, and Hippopus hippopus encountered during the survey, these species were categorized as "Other spp.
1999) also observed reduction in the clearance rates in Tridacna squamosa when exposed to a salinity of 20 for 12-16 h.
The result in this study is in good agreement with the findings for Tridacna squamosa (Blidberg et al.
It was reported that Tridacna squamosa increased its CR in darkness in both ambient and reduced salinity (Blidberg et al.
Physiological responses of the fluted giant clam, Tridacna squamosa, exposed to decreased irradiance and reduced salinity.
the number of clam juveniles attaining this stage divided by the number of all the clam individuals; termed the symbiosis rate in our study) is low: less than 5% for Tridacna crocea Lamarck, 1819, Tridacna derasa (Roding, 1798), and Tridacna squamosa Lamarck, 1819 in general (Iwai & Matsuoka 2005).
2006) examined how light intensity and water temperature influence the symbiosis rates of Tridacna crocea, Tridacna derasa, and Tridacna squamosa.
Spawning, development, and acquisition of zooxanthellae by Tridacna squamosa (Mollusca, Bivalvia).
