This detailed anatomical illustration of a seahorse highlights key structures essential for understanding its biology. The image clearly depicts the gill, located behind the head, which facilitates respiration by extracting oxygen from water. The dorsal fin, prominent along the back, aids in propulsion and maneuverability. The unique bony plates forming the body provide structural support, while the prehensile tail is adapted for grasping. This visual serves as an educational tool in marine biology and patient education, illustrating the seahorse's adaptations for survival in aquatic environments.
