  abstract = {{T}he life history of 15 giant clams, {H}ippopus hippopus, was studied in situ in the southern lagoon of {N}ew {C}aledonia; growth rate and animal behavior were studied both by sclerochronology and high-frequency noninvasive ({HFNI}) valvometry. {E}lectrodes glued on each valve of each specimen recorded the shell-gaping behavior at 0.6-{H}z frequency. {A} nonparametric regression model was used to model clam behavior. {T}he daily increment thickness in the inner layer of five representative clams was measured. {H}. hippopus has its valves open during the day and partly closed during the night all year round, and shell growth is continuous. {T}he cumulative growth using both techniques was similar, as was the mean daily thickness increment. {T}he occurrence of one increment per day in {H}. hippopus shell was measured by valvometry. {T}he five sclerochronological profiles were highly similar. {S}hell growth was significantly correlated to rising sea surface temperature ({SST}), up to 27 degrees {C}. {A}t the solar maximum, gaping behavior and increment thickness became erratic. {SST}- and solar irradiance-related stress could be related to physiological oxidative stress triggered by zooxanthellae symbionts. {I}n the present context of globally increasing {SST}, our data indicate that the giant clams {H}. hippopus could live beyond their thermal comfort limits in summer in {N}ew {C}aledonia.},
