pectoral fins

Chest-level fish appendages

Pectoral fins are the pair of fins located on either side of a fish's body, typically just behind the gills.

They function somewhat like arms or steering paddles, helping fish maneuver, maintain balance, and control their position in the water.

In some species, like flying fish, the pectoral fins are enlarged and enable gliding above the water's surface.

The term pectoral refers to the chest region, where these fins attach.
