Apart from the tail or caudal fin, fins have no direct connection with the spine and are supported by muscles only. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes, such as moving forward, turning, keeping an upright position or stopping.Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling.he pelvic fin assists the fish in going up or down through the water, turning sharply, and stopping quickly. 1  In gobies, the pelvic fins are often fused into a single sucker disk. 2  Pelvic fins can take many positions along the ventral surface of the fish.
