Tiktaalik is considered a transitional fossil because it exhibits both fish-like and tetrapod (four-limbed) characteristics, bridging the evolutionary gap between aquatic and terrestrial life. Its robust, limb-like fins possess structural features akin to the bones of land animals, providing evidence of the evolutionary changes that enabled vertebrates to adapt to life on land. Additionally, the presence of a flattened head and advanced sensory structures reminiscent of early tetrapods highlights the evolutionary adaptations that took place during the transition from water to land.
