    Abstract:
    This study makes a descriptive analysis of necropsied sea turtles registered in the Biota Conservation Institute database between May 2018 and May 2022 on the coast of Alagoas, Brazil. During this period, 79 animals of four species were necropsied: 87.4 % (69) Chelonia mydas, 6.3 % (5) Caretta caretta, 3.8 % (3) Lepidochelys olivacea and 2.5 % (2) Eretmochelys imbricata. C. mydas was the most frequent species, mainly juvenile females. In 29.1 % (23/79) evidence of anthropogenic interactions was found (e.g., fishing net marks, plastic waste in the digestive tract, trauma from collisions with boats). Cutaneous tumors suggestive of fibropapillomatosis in 35.4 % (28/79), in C. mydas and E. imbricata, half were in an area of high eutrophication, close to the capital. Endoparasites were found in 46.8 % (37/79) individuals. Information on strandings in the region is essential for understanding the use of the area and the impacts to which these animals are exposed.
