They could be on the sensor or they could be on any of the intermediate surfaces (such as on / in lenses, filters, etc.). A good way to find them is to take a picture of a cloudless sky. If you have a zoom lens, take 2 shots with the second having the zoom ring turned maybe 1/4 turn. If the spot moves, it's toward the front of the lens. If it is stationary, it is toward the back of the lens or on the sensor.
Because they're much closer than anything else in the image, they're usually out-of-focus. Taking pictures in bright sunlight will make them more distinct as a narrower aperture will give greater depth of field.
Here's an example:
