Short summary

Coral growth rate is known to influence the δ¹⁸O and δ¹³C isotope record to a lesser extent. Recent published data show differences in growth parameters between female and male coral; thus, skeletal δ¹⁸O and δ¹³C are hypothesized to be different in each sex. Our results support the hypothesis of a sex-associated difference in skeletal δ¹⁸O and δ¹³C signal, and suggest that environmental conditions and coral growth parameters affect skeletal isotopic signal differently in each sex.
