These 2 pictures are in sequence, first showing the otter swimming out from the bank, then all beginning their dives to rake through gravel on the bottom of the pool. The mother is completely upside down, the juveniles are scoping out their dive.

Another tip. This is a long subject. I cropped these images to a 12x4 (3:1) format to focus in on the subject. In both images the bodies of the otter for a soft curve, especially the second photo. The curve is accentuated by the long narrow image format.
