Skeletal anatomical, osteotechnical and osteoassembly description of the seagull Larus domimicanus (Lichtenstein – 1823) found dead, in the conservation units of the Jureia-Itatins mosaic, South coast of SP

The southern gull or gull (Larus dominicanus) belongs to the Laridae family. It stands out for being the largest species among the seagulls frequently found in Brazil, reaching approximately 58 cm in length. Identification of these birds can be done through their plumage, which is divided into four distinct age categories. Typically, the female lays two to three eggs, and the responsibility for feeding the young is shared by both parents. The objective is to describe the morphology and skeletal anatomy in order to disseminate knowledge, highlighting the importance of such research for the literature in the area and as a specific objective the assembly of a structure that can help in the identification of the anatomical parts of the species, since it is There are few research specimens for this species. The study took place on the corpse of the animal found dead in the conservation units of the Jureia-Itatins mosaic, on the south coast of São Paulo. Using maceration and bleaching techniques to prepare the skeleton, it was possible to detail the bone structure, providing an understanding of the functionalities related to flight, nutrition and reproduction of this species, in addition to demonstrating the effectiveness and cost-benefit of anatomical preparation methods. adopted. This approach aimed to evaluate the osteomounting procedure, which enabled an improved understanding of the seagull's skeletal structure. Thus, the final assembly of the skeleton became a tool to assist both veterinary medicine and biology students, emphasizing the relevance of the osteology and osteoassembly techniques presented in this work.
