## Abstract

Several diseases affect the coelomic cavity of sea turtles, making accurate anatomical knowledge essential. This study presents an open-access, interactive anatomical atlas of the coelomic cavity of the loggerhead sea turtle (Caretta caretta). The atlas integrates osteology, anatomical dissections, computed tomography (CT), and magnetic resonance imaging (MRI), with labelled and colour-coded anatomical structures. It includes 50 images and provides an educational resource for veterinarians, biologists, researchers, and students involved in sea turtle conservation.

The coelomic cavity of sea turtles is affected by congenital, developmental, traumatic, infectious, and organ- or system-specific disorders, making accurate anatomical knowledge essential for veterinary practice. This study presents an open-access, interactive two-dimensional (2D) anatomical atlas of the coelomic cavity of the loggerhead sea turtle (Caretta caretta), developed using images obtained from osteology, gross anatomical dissections, computed tomography (CT), and magnetic resonance imaging (MRI). The atlas comprises six osteology images, sixteen anatomical dissection images, eight transverse CT images acquired using bone and soft-tissue windows, six three-dimensional (3D) volume-rendered CT images, and fourteen MRI images (four transverse, five dorsal, and five sagittal), all provided in PNG format. Relevant anatomical structures were segmented and colour-coded for each figure using manual layer-based segmentation software. The Unity 3D platform was employed for image visualisation and assessment, supporting the development of interactive two-dimensional content. This atlas serves as a useful interactive tool for anatomical learning and clinical reference for professionals and students engaged in the conservation of loggerhead sea turtles.
