You mean the ones they're using to swim with like little arm paddles? Those are the pectoral fins.

An aircraft flap is simply called a "flap." Flaps are movable surfaces located on the wings of an aircraft. They are designed to change the shape and configuration of the wing during different phases of flight. By extending or retracting the flaps, pilots can adjust the lift and drag characteristics of the aircraft, allowing for changes in speed, angle of descent, and takeoff and landing capabilities. Flaps can be divided into several types, including: Plain Flaps: These are the simplest type of flaps, which extend straight down from the wing when deployed. Split Flaps: These flaps are divided into two sections, with the lower section extending downward and the upper section remaining in place. Slotted Flaps: Slotted flaps have a slot or gap between the wing and the flap, which helps to increase lift at lower speeds. Fowler Flaps: Fowler flaps extend backward and downward, increasing both the wing area and camber, which allows for greater lift generation. The specific type of flap used on an aircraft depends on its design and intended purpose. Flaps play a crucial role in controlling and maneuvering an aircraft, particularly during takeoff and landing.
they're called valves. they are found in veins and also in the heart. hope this helped!

No, in fact the flying fish can't fly, it glides how ever, a fresh water species called a hatchet fish is the only true flying fish as it flaps it's pectoral fins to achieve flight
It flaps its fins really hard.
They are quite literally called flaps, and they make the plane go up, down, left and right.
