Abstract
Strandings provide valuable information about rare marine organisms and their relationship with their environment. In the southern Gulf of México, specifically on the central coast of Campeche, Mexico, strandings of oceanic cetaceans have rarely been recorded, therefore, biological information has also been scarce. One of such rare stranding cases occurred on September 7, 2022, on the coast of Seybaplaya, Campeche. The specimen was identified as a female of Tursiops truncatus with the morphology features of the oceanic ecotype. The carcass was examined shortly after death, and samples for different analyses were obtained fresh. Tissue samples were collected, and some particular observations were made to define the individual's general health status. Results of the analyses revealed damage in the liver, lungs, and kidneys, probably related to 1) the advanced age of the organism (>35 years), and 2) the presence of persistent organic pollutants. Most importantly, this study contributed two new findings, the first record of the parasite Anisakis and the presence of renal calculi in the oceanic ecotype of T. truncatus in the southern Gulf of Mexico.
