Most fish have 2 types of fins: single fins that are found along the centerline (top and bottom) of the fish, and paired fins. The caudal fin, or tail fin, is the main fin used to move the fish forward in the water, while the dorsal and anal fins (on the top and bottom, respectively) help the fish balance and.Essay on the ichthyology of Port Jackson.

Limbs originated from paired fish fins are an important innovation in Gnathostomata. Many studies have focused on limb development-related genes, of which the T-box transcription factor 4 gene (tbx4) has been considered as one of the most essential factors in the regulation of the hindlimb development. We previously confirmed pelvic fin loss in tbx4-knockout zebrafish.
