Abstract excerpt

This study examines regional and genetic influences on shell morphology of the small giant clam Tridacna maxima from the central and northern Red Sea of Saudi Arabia using linear mixed model and geometric morphometrics. Shell height and length exhibit significant regional differences, with individuals from the North showing greater dimensions (height: F1,17 = 12.102, p = 0.003; length: F1,17 = 9.219, p = 0.007)...
