Snakelike or fish like movements.
arm movement: face backs of hands towards each other and push out wards ( like if you were parting some vines) leg movement: outwards and back in a circular motion in the water. Your whole body goes underwater, you do the arm movement and leg movement,c ome up, take breath, repeat. Sorry, kind of vague, feel free to improve my answer.
The biceps flexes the arm it does not extend it (straightens). The triceps brachii extends the arm. They do work together. If one is damaged and doesn't work as it should, the movement will be "jerky" and not smooth.
Sometimes it is a prosthetic arm.
No, it shouldn't make any kind of peculiar noise at all.
No, and the muscle that controls the movement is the piloerector muscle. See piloerector which are smooth muscle (involuntary)
