  "abstract": "Stable zinc isotopes (δ 66 Zn) have recently emerged as promising ecological tracers, yet their application in elasmobranchs remains limited. Here, we evaluated the use of δ 66 Zn in elasmobranch muscle tissue in combination with traditional isotopes (δ 13 C and δ 15 N) to compare isotopic variability among three sympatric stingray species inhabiting a heterogeneous coastal system along the Brazilian coast. The analyses revealed species-specific δ 66 Zn patterns and differences in multitracer isotopic space among species. Hypanus guttatus exhibited broader isotopic variability than Hypanus marianae and Hypanus berthalutzae , which showed more constrained and partially overlapping isotopic patterns. Compared with δ 13 C and δ 15 N, δ 66 Zn exhibited partially distinct isotopic behaviour, suggesting sensitivity to a more complex combination of trophic, environmental, and physiological influences. This additional isotopic variability contributed complementary information to species discrimination. Overall, our results suggest that Zn isotopes in soft tissues represent a promising addition to multitracer isotopic approaches in marine predators.",
