This grayscale line-art illustration depicts the complete postcranial and cranial skeleton of a bottlenose dolphin (Tursiops truncatus), emphasizing adaptations for aquatic locomotion such as the shortened neck, robust ribcage, and fused vertebrae in the tail region. The image clearly shows the heterodont dentition, pectoral flipper phalanges, and pelvic vestiges, offering insight into cetacean evolution from terrestrial ancestors. Minor bone fragments near the caudal end suggest fossil or excavation context.

Used in educational websites, museum exhibits, or academic articles about cetacean anatomy, evolutionary biology, or marine paleontology; serves users seeking visual reference for comparative anatomy or science communication.
