Posterior paired fins, located in the abdominal position or towards the rear.
A pair of fins on a fish located directly below the gills. Not all marine fish have these.
The pair of fins located on the underside of the body, often underneath the pectoral fins. These may be quite small in some species, and very long in others.
These fins are located near the lower portion of the fish's body near the head region.
These are positioned below the pectoral fins and assist with controlling the direction of the fish and also help it to maintain a hovering position. They are also used for “braking”.
These are the fins that are located just forward of the anal fin.
